CVE-2026-52778
Description détaillée
YesWiki is a wiki system written in PHP. Prior to version 4.6.6, an unsafe execution vulnerability exists in the Bazar form field calculator (CalcField.php) of YesWiki. The application attempts to sanitize user-defined mathematical formulas using a complex recursive regular expression before passing them to the PHP eval() function. This implementation is inherently flawed: it is vulnerable to Regular Expression Denial of Service (ReDoS / Stack Overflow) which can crash the server, and it creates a high-risk architecture where any logic bypass directly results in arbitrary PHP code execution. Version 4.6.6 patches the issue.

CVE-2026-49141
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-2026-47345
Namespace attributes are not encoded correctly during HTML serialization. This allows bypassing the cross-site scripting prevention mechanism of typo3/html-sanitizer before version 2.3.2.
CVE-2026-47344
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.
