Versions prior to 2.9.1 can generate and execute attacker-controlled PHP code when `JmesPath\\CompilerRuntime` is used with an attacker-controlled JMESPath expression. The compiler emits parsed JMESPath function names into generated PHP source without sufficient escaping. A crafted expression can cause the generated cache file to contain executable attacker-controlled PHP, which is then loaded by the compiler runtime. The issue is patched in `2.9.1` and later. As a workaround, disable `JP_PHP_COMPILE` and do not use `JmesPath\\CompilerRuntime` with attacker-controlled expressions. Use the default `AstRuntime` for untrusted expressions. Applications that must continue accepting untrusted JMESPath expressions before upgrading should ensure those expressions are never evaluated by the compiler runtime."}], "lastModified": "2026-06-17T10:58:10.890", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:jmespath:jmespath:*:*:*:*:*:php:*:*", "vulnerable": true, "matchCriteriaId": "2F2D7DD9-AC56-45ED-AD62-DC5023908049", "versionEndExcluding": "2.9.1"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
