Description
pypdf: Manipulated XMP metadata streams can exhaust RAM
Impact
An attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing large XMP metadata, possibly with lots of unnecessary elements.
Patches
This has been fixed in pypdf==6.12.1.
Workarounds
If you cannot upgrade yet, consider applying the changes from PR #3796.
Mitigation
Minimal update. May introduce new vulnerabilities or breaking changes.
