CVE-2026-49141
SUMMARY

WACRM prior to commit 73041bf contain an authorization bypass vulnerability in the automation engine that allows authenticated attackers to access and modify contacts belonging to other tenants by supplying an arbitrary caller-controlled contact_id in the POST request body without tenant ownership verification. Attackers can exploit the service-role client that bypasses row-level security to modify victim contact fields including name, email, and company across tenant boundaries using only a known contact UUID.

CVE-2026-47344
SUMMARY

When ALLOW_INSECURE_RAW_TEXT is enabled, whitespace-variant closing tags (e.g., </style\t>) are not recognized by the sanitizer but accepted by browsers as valid end tags, allowing subsequent content to escape sanitization. This allows bypassing the cross-site scripting prevention mechanism of typo3/html-sanitizer before version 2.3.2.
