GHSA-9frc-8383-795m | Symfony's YAML Parser has a ReDoS via Catastrophic Backtracking in Parser::cleanup() Regex |
Tue, 14 Jul 2026 19:00:00 +0000
| Type | Values Removed | Values Added |
|---|---|---|
| Description | Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.52, 6.4.40, 7.4.12, and 8.0.12, Symfony\Component\Yaml\Parser::cleanup() used regular expressions with overlapping quantifiers for YAML directive, comment, and document marker cleanup, allowing crafted input to make parsing hang for an arbitrarily long time. This issue is fixed in versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12. | |
