Package : python-html-sanitizer
Version : 1.9.1-2+deb11u1
CVE ID : CVE-2024-34078
Debian Bug : 1070710
It was discovered that there was a sanitisation bypass issue in
python-html-sanitizer, a library used ensure that user-specified
content cannot inject HTML or JavaScript into a webpage.
If the default "keep_typographic_whitespace=False" value was set,
malicous users could have exploited the fact that some Unicode
characters normalise to chevrons, which allowed specially-crafted
HTML to escape sanitization.
For Debian 11 bullseye, this problem has been fixed in version
1.9.1-2+deb11u1.
We recommend that you upgrade your python-html-sanitizer packages.
For the detailed security status of python-html-sanitizer please refer to
