What is CVE-2026-124622?
CVE-2026-124622 is a medium-severity vulnerability in olivier-ls PHP-FTS, published on 9 Nov 2026.
Official description
A vulnerability was identified in olivier-ls PHP-FTS up to 1.1.3. This impacts the function TrigramIndex::open of the file Storage.php. Such manipulation leads to time-of-check time-of-use. The attack needs to be performed locally. Upgrading to version 1.1.4 will fix this issue. The name of the patch is 0b2fae333d6b022da7ed4c43e2d41aa03f91dff3. Upgrading the affected component is recommended. The project maintainer explains: "[T]he attack requires write access to the index directory by a user other than the one running the application. That is a real shared-hosting scenario and worth defending against, which is why it is fixed but it is a hardening measure rather than a remotely reachable vulnerability, and the "Code Execution" impact additionally assumes the symlink target is a web-served .php file."
