6.1

Medium

VectorAV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Name of the Vulnerable Software and Affected Versions lxml versions prior to 3.3.5
Description The issue is related to an incomplete blacklist vulnerability in the lxml.html.clean module, which allows remote attackers to conduct cross-site scripting (XSS) attacks via control characters in the link scheme to the clean html function. This can lead to a violation of the integrity of protected information. The exploitation of this vulnerability can be carried out remotely.
Recommendations For versions prior to 3.3.5, update to version 3.3.5 or later to resolve the issue. As a temporary workaround, consider restricting the use of the lxml.html.clean module until a patch is available. Avoid using the clean html function in the affected module to minimize the risk of exploitation.
