==4.5.2→==6.1.0lxml vulnerable to Cross-site Scripting
CVE-2020-27783 / GHSA-pgww-xf46-h92r
More information
Details
A XSS vulnerability was discovered in python-lxml's clean module. The module's parser didn't properly imitate browsers, which caused different behaviors between the sanitizer and the user's page. A remote attacker could exploit this flaw to run arbitrary HTML/JS code.

lxml vulnerable to Cross-Site Scripting
CVE-2021-28957 / GHSA-jq4v-f5q6-mjqq
More information
Details
An XSS vulnerability was discovered in the python
lxmlclean module versions before 4.6.3. When disablingthe safe_attrs_onlyandformsarguments, theCleanerclass does not remove theformactionattribute allowing for JS to bypass the sanitizer. A remote attacker could exploit this flaw to run arbitrary JS code on users who interact with incorrectly sanitized HTML. This issue is patched inlxml4.6.3.Severity

lxml's HTML Cleaner allows crafted and SVG embedded scripts to pass through
CVE-2021-43818 / GHSA-55x5-fj6c-h6m8
More information
Details
Impact
The HTML Cleaner in lxml.html lets certain crafted script content pass through, as well as script content in SVG files embedded using data URIs.
Users that employ the HTML cleaner in a security relevant context should upgrade to lxml 4.6.5.
Patches
The issue has been resolved in lxml 4.6.5.
Workarounds
None.

lxml NULL Pointer Dereference allows attackers to cause a denial of service
CVE-2022-2309 / GHSA-wrxv-2j5q-m38w
More information
Details
NULL Pointer Dereference allows attackers to cause a denial of service (or application crash). This only applies when lxml is used together with libxml2 2.9.10 through 2.9.14. libxml2 2.9.9 and earlier are not affected. It allows triggering crashes through forged input data, given a vulnerable code sequence in the application. The vulnerability is caused by the iterwalk function (also used by the canonicalize function). Such code shouldn't be in wide-spread use, given that parsing + iterwalk would usually be replaced with the more efficient iterparse function. However, an XML converter that serialises to C14N would also be vulnerable, for example, and there are legitimate use cases for this code sequence. If untrusted input is received (also remotely) and processed via iterwalk function, a crash can be triggered.

lxml: Default configuration of iterparse() and ETCompatXMLParser() allows XXE to local files
CVE-2026-41066 / GHSA-vfmq-68hx-4jfw
More information
Details
Impact
Using either of the two parsers in the default configuration (with
resolve_entities=True) allows untrusted XML input to read local files.Patches
lxml 6.1.0 changes the default to
resolve_entities='internal', thus disallowing local file access by default.Workarounds
Setting the
resolve_entitiesoption explicitly toresolve_entities='internal'orresolve_entities=Falsedisables the local file access.Resources
Original report: https://bugs.launchpad.net/lxml/+bug/2146291
The default option was changed to
resolve_entities='internal'for the normal XML and HTML parsers in lxml 5.0. The default was not changed foriterparse()andETCompatXMLParser()at the time. lxml 6.1 makes the safe option the default for all parsers.Severity

Release Notes
lxml/lxml (lxml)
v6.1.0Compare Source
==================
This release fixes a possible external entity injection (XXE) vulnerability in
iterparse()and theETCompatXMLParser.Features added
GH#486: The HTML ARIA accessibility attributes were added to the set of safe attributes
in
lxml.html.defs. This allowslxml_html_cleanto pass them through.Patch by oomsveta.
The default chunk size for reading from file-likes in
iterparse()is now configurablewith a new
chunk_sizeargument.Bugs fixed
resolve_entitiesoption was still set toTrueforiterparseandETCompatXMLParser, allowing for external entity injection (XXE)when using these parsers without setting this option explicitly.
The default was now changed to
'internal'only (as for the normal XML and HTML parserssince lxml 5.0).
Issue found by Sihao Qiu as CVE-2026-41066.

Binary wheels use zlib 1.3.2.
v6.0.2Compare Source
==================
Bugs fixed
LP#2125278: Compilation with libxml2 2.15.0 failed.
Original patch by Xi Ruoyao.
Setting
decompress=Truein the parser had no effect in libxml2 2.15.Binary wheels on Linux and macOS use the library version libxml2 2.14.6.
See https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.14.6
Test failures in libxml2 2.15.0 were fixed.
Other changes
Binary wheels for Py3.9-3.11 on the
riscv64architecture were added.Error constants were updated to match libxml2 2.15.0.
Built using Cython 3.1.4.
v6.0.1Compare Source

lxml.sax._getNsTag()could fail with an exception on malformed input.GH#467: Some test adaptations were made for libxml2 2.15.
Patch by Nick Wellnhofer.
LP2119510, GH#473: A Python compatibility test was fixed for Python 3.14+.
Patch by Lumír Balhar.
GH#471: Wheels for "riscv64" on recent Python versions were added.

See https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.14.5
Windows binary wheels continue to use a security patched library version libxml2 2.11.9.
v6.0.0Compare Source
==================
Features added
GH#463:
lxml.html.diffis faster and provides structurally better diffs.Original patch by Steven Fernandez.
GH#405: The factories
ElementandElementTreecan now be used in type hints.GH#448: Parsing from
memoryviewand other buffers is supported to allow zero-copy parsing.GH#437:
lxml.html.builderwas missing several HTML5 tag names.Patch by Nick Tarleton.
GH#458:
CDATAcan now be written into the incrementalxmlfile()writer.Original patch by Lane Shaw.
A new parser option
decompress=Falsewas added that controls the automaticinput decompression when using libxml2 2.15.0 or later. Disabling this option
by default will effectively prevent decompression bombs when handling untrusted
input. Code that depends on automatic decompression must enable this option.
Note that libxml2 2.15.0 was not released yet, so this option currently has no
effect but can already be used.
The set of compile time / runtime supported libxml2 feature names is available as
etree.LIBXML_COMPILED_FEATURESandetree.LIBXML_FEATURES.This currently includes
catalog,ftp,html,http,iconv,icu,lzma,regexp,schematron,xmlschema,xpath,zlib.Bugs fixed
GH#353: Predicates in
.find*()could mishandle tag indices if a default namespace is provided.Original patch by Luise K.
GH#272: The
headandbodyproperties oflxml.htmlelements failed if no such elementwas found. They now return
Noneinstead.Original patch by FVolral.
Tag names provided by code (API, not data) that are longer than
INT_MAXcould be truncated or mishandled in other ways.
.text_content()onlxml.htmlelements accidentally returned a "smart string"without additional information. It now returns a plain string.
LP#2109931: When building lxml with coverage reporting, it now disables the
sys.monitoringsupport due to the lack of support in nedbat/coveragepy#1790
Other changes
Support for Python < 3.8 was removed.
Parsing directly from zlib (or lzma) compressed data is now considered an optional
feature in lxml. It may get removed from libxml2 at some point for security reasons
(compression bombs) and is therefore no longer guaranteed to be available in lxml.
As of this release, zlib support is still normally available in the binary wheels
but may get disabled or removed in later (x.y.0) releases. To test the availability,
use
"zlib" in etree.LIBXML_FEATURES.The
Schematronclass is deprecated and will become non-functional in a future lxml version.The feature will soon be removed from libxml2 and stop being available.
GH#438: Wheels include the
arm7ltarget.GH#465: Windows wheels include the
arm64target.Patch by Finn Womack.
Binary wheels use the library versions libxml2 2.14.4 and libxslt 1.1.43.
Note that this disables direct HTTP and FTP support for parsing from URLs.
Use Python URL request tools instead (which usually also support HTTPS).
To test the availability, use
"http" in etree.LIBXML_FEATURES.Windows binary wheels use the library versions libxml2 2.11.9, libxslt 1.1.39 and libiconv 1.17.
They are now based on VS-2022.
Built using Cython 3.1.2.
The debug methods
MemDebug.dump()andMemDebug.show()were removed completely.libxml2 2.13.0 discarded this feature.

v5.2.0Compare Source
==================
Other changes
LP#1958539: The
lxml.html.cleanimplementation suffered from several (only if used)security issues in the past and was now extracted into a separate library:
https://github.com/fedora-python/lxml_html_clean
Projects that use lxml without "lxml.html.clean" will not notice any difference,
except that they won't have potentially vulnerable code installed.
The module is available as an "extra" setuptools dependency "lxml[html_clean]",
so that Projects that need "lxml.html.clean" will need to switch their requirements
from "lxml" to "lxml[html_clean]", or install the new library themselves.
The minimum CPU architecture for the Linux x86 binary wheels was upgraded to
"sandybridge" (launched 2011), and glibc 2.28 / gcc 12 (manylinux_2_28) wheels were added.

Patch by Michael Schlenker.
A compile problem with recent libxml2 2.12.x versions was resolved.
The internal exception handling in C callbacks was improved for Cython 3.0.
The exception declarations of
xmlInputReadCallback,xmlInputCloseCallback,xmlOutputWriteCallbackandxmlOutputCloseCallbackintree.pxdwerecorrected to prevent running Python code or calling into the C-API with a live

LP#1522052: A file-system specific test is now optional and should no longer fail
on systems that don't support it.
GH#392: Some tests were adapted for libxml2 2.13.
Patch by Nick Wellnhofer.
Contains all fixes from lxml 4.9.4.
Other changes
LP#1742885: lxml no longer expands external entities (XXE) by default to prevent
the security risk of loading arbitrary files and URLs. If this feature is needed,
it can be enabled in a backwards compatible way by using a parser with the option
resolve_entities=True. The new default isresolve_entities='internal'.With libxml2 2.10.4 and later (as provided by the lxml 5.0 binary wheels),
parsing HTML tags with "prefixes" no longer builds a namespace dictionary
in
nsmapbut considers theprefix:namestring the actual tag name.With older libxml2 versions, since 2.9.11, the prefix was removed. Before
that, the prefix was parsed as XML prefix.
lxml 5.0 does not try to hide this difference but now changes the ElementPath
implementation to let
element.find("part1:part2")search for the tagpart1:part2in documents parsed as HTML, instead of looking only forpart2.LP#2024343: The validation of the schema file itself is now optional in the
ISO-Schematron implementation. This was done because some lxml distributions
discard the RNG validation schema file due to licensing issues. The validation
can now always be disabled with
Schematron(..., validate_schema=False).It is enabled by default if available and disabled otherwise. The module
constant
lxml.isoschematron.schematron_schema_valid_supportedcan be usedto detect whether schema file validation is available.
Some redundant and long deprecated methods were removed:
parser.setElementClassLookup(),xslt_transform.apply(),xpath.evaluate().Some incorrect declarations were removed from
python.pxd. In general, this fileshould not be used by external Cython code. Use the C-API declarations provided by
Cython itself instead.
Binary wheels use the library versions libxml2 2.12.3 and libxslt 1.1.39.
