CVE-2024-37388 2 Dnkorpushov, Lxml 2 Ebookmeta, Lxml 2024-10-30 9.1 Critical
An XML External Entity (XXE) vulnerability in the ebookmeta.get_metadata function of lxml before v4.9.1 allows attackers to access sensitive information or cause a Denial of Service (DoS) via crafted XML input.
CVE-2014-3146 1 Lxml 1 Lxml 2024-08-06 N/A
Incomplete blacklist vulnerability in the lxml.html.clean module in lxml before 3.3.5 allows remote attackers to conduct cross-site scripting (XSS) attacks via control characters in the link scheme to the clean_html function.
CVE-2018-19787 3 Canonical, Debian, Lxml 3 Ubuntu Linux, Debian Linux, Lxml 2024-08-05 N/A
An issue was discovered in lxml before 4.2.5. lxml/html/clean.py in the lxml.html.clean module does not remove javascript: URLs that use escaping, allowing a remote attacker to conduct XSS attacks, as demonstrated by "j a v a s c r i p t:" in Internet Explorer. This is a similar issue to CVE-2014-3146.
CVE-2020-27783 6 Debian, Fedoraproject, Lxml and 3 more 9 Debian Linux, Fedora, Lxml and 6 more 2024-08-04 6.1 Medium
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.
CVE-2021-43818 6 Debian, Fedoraproject, Lxml and 3 more 16 Debian Linux, Fedora, Lxml and 13 more 2024-08-04 8.2 High
lxml is a library for processing XML and HTML in the Python language. Prior to version 4.6.5, 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 to receive a patch. There are no known workarounds available.
CVE-2021-28957 6 Debian, Fedoraproject, Lxml and 3 more 7 Debian Linux, Fedora, Lxml and 4 more 2024-08-03 6.1 Medium
An XSS vulnerability was discovered in python-lxml's clean module versions before 4.6.3. When disabling the safe_attrs_only and forms arguments, the Cleaner class does not remove the formaction attribute 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 in lxml 4.6.3.
CVE-2022-2309 4 Fedoraproject, Lxml, Redhat and 1 more 4 Fedora, Lxml, Enterprise Linux and 1 more 2024-08-03 7.5 High
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.
