GHSA-RF5M-H8Q9-9W6Q Information Disclosure in TYPO3 Page Tree

Problem Backend users could see items in the backend page tree without having access if the mounts pointed to pages restricted for their user/group, or if no mounts were configured but the pages allowed access to "everybody." However, affected users could not manipulate these pages. Solution Upda...

GHSA-RJ3X-WVC6-5J66 TYPO3 vulnerable to Improper Access Control Persisting File Abstraction Layer Entities via Data Handler

Problem Entities of the File Abstraction Layer FAL could be persisted directly via DataHandler. This allowed attackers to reference files in the fallback storage directly and retrieve their file names and contents. The fallback storage "zero-storage" is used as a backward compatibility layer for...

GHSA-38R2-5695-334W TYPO3 Backend Forms vulnerable to Information Disclosure of Hashed Passwords

Problem Password hashes were being reflected in the editing forms of the TYPO3 backend user interface. This allowed attackers to crack the plaintext password using brute force techniques. Exploiting this vulnerability requires a valid backend user account. Solution Update to TYPO3 versions 8.7.57...

TYPO3 HTML Sanitizer Bypasses Cross-Site Scripting Protection

Meta CVSS: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:F/RL:O/RC:C 5.7 Problem Due to a parsing issue in upstream package masterminds/html5, malicious markup used in a sequence with special HTML comments cannot be filtered and sanitized. This allows to by-pass the cross-site scripting mechanis...
