Hi,

The following vulnerability was published for perl.

CVE-2026-82560[0]:
| Pod::Text versions before 6.1.1 for Perl allow CPU and memory
| exhaustion formatting a POD document whose =over nesting drives the
| margin to the output width.  Each =over adds its indent to the
| margin, which wrap() subtracts from the output width to get the
| space available for text. When that space reaches zero, the line-
| splitting substitution matches the empty string, and the loop
| consumes no input while appending the margin padding on every pass.
| Formatting an attacker-supplied POD document never returns, and the
| output grows until memory is exhausted.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
