+  "summary": "Apptainer has incorrect path matching for 'limit container paths' directive ",
+  "details": "### Impact\n\nThe `limit container paths directive` in `apptainer.conf` is intended to allow a system administrator limit the paths from which containers can be run, under setuid mode. Due to incorrect matching of a path string, sibling directories with similar names may incorrectly be allowed.\n\nFor example, the configuration:\n```\nlimit container paths = /data/safe\n```\nWill also allow containers in /data/safe-but-unsafe to be run.\n\n### Patches\n\nThe issue is patched in apptainer version 1.5.1.\n\n### Workarounds\n\nIf developers do not use setuid mode or do not use the `limit container paths` functionality, then this issue does not affect their installation. Note that, as documented [1], if user namespaces are allowed for unrestricted use then this functionality does not stop users from running any container of their choice.\n\nIf developers do use the `limit container paths` functionality they are advised to update.\n\n### Credit\n\nThis vulnerability was discovered and disclosed to the Apptainer project by Dave Trudgian of Sylabs.\n\n### Resources\n\n[1] https://apptainer.org/docs/admin/latest/configfiles.html#limiting-container-execution",
