### Summary `matchesExecAllowlistPattern` normalized patterns and targets with lowercasing and compiled glob matching too broadly on POSIX. In addition, the `?` wildcard could match `/`, which allowed matches to cross path segments. ### Impact These matching rules could overmatch allowlist entries and permit commands or executable paths that an operator did not intend to approve. ### Affected versions `openclaw` `<= 2026.3.8` ### Patch Fixed in `openclaw` `2026.3.11` and included in later releases such as `2026.3.12`. Exec allowlist matching now respects the intended path semantics, and regression tests cover the POSIX case-folding and slash-crossing cases.
