Description Jon Moroney 2026-07-09 20:10:30 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

The incremental HTML parser (html.parser.HTMLParser) allows for CPU
denial-of-service through repeated unterminated markup declarations when
processing uncontrolled data.
Comment 1 Aoife Moloney 2026-08-17 15:16:48 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
Comment 2 Michel Lind 2026-10-06 13:15:24 UTC 
This CVE is in the language interpreter and is fixed by the interpreter's own update; this package only uses the affected module and needs no change of its own.
