CVE-2026-38970: n/a
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.
AI Analysis
Technical Summary
CVE-2026-38970 is a denial-of-service vulnerability in pdfcpu through version 0.11.1. The vulnerability exists in the parser implementation within pkg/pdfcpu/model/parse.go, where recursive descent through nested PDF objects, including arrays, is performed by ParseObjectContext() and parseArray() functions without enforcing a maximum nesting depth. This uncontrolled recursion can lead to a denial-of-service condition by exhausting stack or processing resources.
Potential Impact
An attacker can craft a malicious PDF with deeply nested objects to trigger uncontrolled recursion in the parser, causing a denial-of-service by crashing or hanging the application. There is no impact on confidentiality or integrity, only availability is affected.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider limiting input size or nesting depth at the application level if possible. Monitor for updates from the pdfcpu project regarding an official fix.
