In OpenBao, when restricted identity templating in an ACL policy hit a blocked wildcard value, parsePaths skipped the affected path instead of failing, so a narrow deny rule nested inside a broader wildcard grant was silently dropped and the broader grant applied. Affects OpenBao 2.6.0 through 2.6.2; fixed in 2.6.3 and 2.7.0 (GHSA-hr5j-3j78-4vh2).
