Description Keith Grant 2026-07-07 14:55:08 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.

pdfcpu through v0.11.1 contains an uncontrolled-recursion denial-of-service issue in pkg/pdfcpu/model/parse.go. The parser descends recursively through nested PDF objects, including arrays, via ParseObjectContext() and parseArray() without enforcing a maximum nesting depth.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
