Prior to version 1.7.42, the patch for CVE-2022-2073, a server-side template injection vulnerability in Grav leveraging the default `filter()` function, did not block other built-in functions exposed by Twig's Core Extension that could be used to invoke arbitrary unsafe functions, thereby allowing for remote code execution. A patch in version 1.74.2 overrides the built-in Twig `map()` and `reduce()` filter functions in `system/src/Grav/Common/Twig/Extension/GravExtension.php` to validate the argument passed to the filter in `$arrow`."}],"source":{"advisory":"GHSA-whr7-m3f8-mpm8","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T16:10:06.973Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/getgrav/grav/security/advisories/GHSA-whr7-m3f8-mpm8","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/getgrav/grav/security/advisories/GHSA-whr7-m3f8-mpm8"},{"name":"https://github.com/getgrav/grav/commit/8c2c1cb72611a399f13423fc6d0e1d998c03e5c8","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/getgrav/grav/commit/8c2c1cb72611a399f13423fc6d0e1d998c03e5c8"},{"name":"https://github.com/twigphp/Twig/blob/v1.44.7/src/Environment.php#L148","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/twigphp/Twig/blob/v1.44.7/src/Environment.php#L148"},{"name":"https://huntr.dev/bounties/3ef640e6-9e25-4ecb-8ec1-64311d63fe66/","tags":["x_refsource_MISC","x_transferred"],"url":"https://huntr.dev/bounties/3ef640e6-9e25-4ecb-8ec1-64311d63fe66/"},{"name":"https://www.github.com/getgrav/grav/commit/9d6a2dba09fd4e56f5cdfb9a399caea355bfeb83","tags":["x_refsource_MISC","x_transferred"],"url":"https://www.github.com/getgrav/grav/commit/9d6a2dba09fd4e56f5cdfb9a399caea355bfeb83"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-12-18T21:38:33.590208Z","id":"CVE-2023-34448","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-12-18T21:38:44.207Z"}}]}}
