CVE-2026-82560
N/A
Summary
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.
Affected Software
| Vendor | Product | Version Range | Status |
|---|---|---|---|
0 < 6.1.1 | affected | ||

Weaknesses
- CWE-835: CWE-835 Loop with Unreachable Exit Condition ('Infinite Loop')
Workarounds
Until a Perl release carries the fix, install podlators v6.1.1 or later, which takes precedence over the bundled copy.
