CVE-2026-82560: Perl Pod::Text denial of service via pathological =over nesting

CVE-2026-82560 · Severity: high · CVSS 7.5 · Published 2026-09-19

Pod::Text is a Perl module that converts POD (Plain Old Documentation) format into plain text. An attacker can craft a malicious POD document with deeply nested =over directives that causes the formatter to hang indefinitely and consume all available memory, preventing legitimate use of systems that process untrusted documentation.

Vendors: Perl.

Technical details

The vulnerability exists in the wrap() method where deeply nested =over directives cause the margin to equal or exceed the output width, creating a pathological condition where the line-splitting regex matches an empty string on every pass. This causes an infinite loop that appends margin padding to the output, exhausting memory and CPU resources. The fix adds a validation check to detect when margin width exceeds output width and forces the margin to zero, preventing the infinite loop.
