| Package | Affected versions | Patched versions |
|---|---|---|
| semantic mediawiki | ≥ 3.0.0, < 7.3.1 | 7.3.1 |
Semantic MediaWiki 3.0.0 before 7.3.1 contains an uncontrolled recursion vulnerability in LegacyParser::getSubqueryDescription() that processes nested query tokens before depth limits apply. Unauthenticated attackers can submit deeply nested query elements to the action=ask API to consume substantial CPU and memory, tying up request workers.
