DOMPurify before 3.4.0 contains a logic error in the ADD_TAGS function where short-circuit evaluation allows forbidden tags to bypass FORBID_TAGS restrictions. Attackers can craft input containing tags listed in FORBID_TAGS that are also added via ADD_TAGS function, causing them to be retained in sanitized output.

CVE-2026-672078.8 HIG—
———Wolf CMS through 0.8.3.1 contains an authorization bypass vulnerability in BackupRestoreController that allows authenticated non-administrative users to access restricted backup functionality due to a PHP operator precedence flaw in the permission check expression. Attackers can exploit the incorrect evaluation of the access control expression to create, download, and restore backups without administrative privileges.10hCVE-2026-48032—23.3%
——7Hulumi is an open-source toolkit that ships secure-by-default cloud and platform infrastructure components for Pulumi. Prior to version 1.4.0, IAM-role policy checks can be bypassed when the role trusts multiple OIDC providers. This issue has been patched in version 1.4.0.13hCVE-2026-557718.8 HIG27.1%
——8CedarJava is an open source Java implementation of the Cedar policy language, used for fine-grained authorization decisions. In versions prior to 4.9.0, the EntityIdentifier.equals() has inverted null/self branches which could lead to incorrect equality comparisons. The EntityIdentifier.equals() method has inverted logic for null and self-reference checks, returning true for null comparisons and false for self-comparisons. This does not affect Cedar authorization decisions (computed in Rust from JSON), but could affect integrators who perform their own equality checks on entity identifiers. This issue has been fixed in version 4.9.0.17dCVE-2026-226607.2 HIG25.3%
——8FlaskBB through 2.2.0, fixed in commit a5da9a5, contains a logic flaw vulnerability that allows authenticated administrators to delete all built-in authorization groups by exploiting a type mismatch in the bulk delete protection check. The bulk AJAX endpoint in the management views compares received JSON integer group IDs against string literals, causing the protection check to always pass, which allows deletion of all six built-in groups and destroys the forum's permission model, potentially rendering the site unusable.17dCVE-2026-598906.1 MED33.2%
——10setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. Prior to 83.0.0, FileList applied MANIFEST.in exclude, global-exclude, recursive-exclude, and prune directives by matching compiled glob patterns against on-disk file names without Unicode normalization, so on macOS APFS or HFS+ an NFD file name could bypass an NFC exclusion rule and be packed into a source distribution. This issue is fixed in version 83.0.0.18dCVE-2026-146875.3 MED25.7%
——8A vulnerability was determined in 666ghj BettaFish up to 1.2.1. Impacted is the function _deduplicate_results of the file InsightEngine/agent.py of the component InsightEngine search-result Deduplication. Executing a manipulation can lead to partial string comparison. The attack can be launched remotely. The exploit has been publicly disclosed and may be utilized. The pull request to fix this issue awaits acceptance.24d
