{"id":"CVE-2026-45756","aliases":["GHSA-8v8v-g73j-492j"],"url":"https://o3.security/vulnerability/CVE-2026-45756","summary":"Symfony: JsonPath Evaluates Attacker-Controlled Regular Expressions in match()/search() Without Limits — ReDoS","details":"Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From 7.3.0-BETA1 until 7.4.12 and 8.0.12, the JsonPath component compiles attacker-controlled match() and search() filter patterns directly into preg_match() without a length cap, i-regexp restriction, or bounded backtracking, allowing catastrophic-backtracking expressions to pin worker CPU and cause denial of service. This issue is fixed in versions 7.4.12 and 8.0.12.","published":"2026-07-14T17:57:03.811Z","modified":"2026-08-12T03:51:48.236619024Z","cvss":null,"epss":{"score":0.00598,"percentile":0.45813,"asOf":"2026-08-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"symfony/json-path","fixedVersion":"7.4.12"},{"ecosystem":"Packagist","name":"symfony/json-path","fixedVersion":"8.0.12"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"7.4.12"},{"ecosystem":"Packagist","name":"symfony/symfony","fixedVersion":"8.0.12"}],"fix":{"url":"https://github.com/symfony/symfony/commit/1ac2d47418ec23066112db1e6ca35be6fe123d14","label":"symfony/symfony@1ac2d47"},"references":[{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v7.4.12"},{"type":"WEB","url":"https://github.com/symfony/symfony/releases/tag/v8.0.12"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45756.json"},{"type":"ADVISORY","url":"https://github.com/symfony/symfony/security/advisories/GHSA-8v8v-g73j-492j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45756"},{"type":"FIX","url":"https://github.com/symfony/symfony/commit/1ac2d47418ec23066112db1e6ca35be6fe123d14"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:48.236619024Z"}}
