The weDocs: AI Powered Knowledge Base, Docs, Documentation, Wiki & AI Chatbot plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'connectorWidth' Block Attribute in all versions up to, and including, 2.3.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AnalysisAI
Stored Cross-Site Scripting in the weDocs WordPress plugin (all versions through 2.3.0) allows authenticated contributors to inject persistent malicious scripts via the unsanitized 'connectorWidth' block attribute in the Sidebar block renderer (render.php lines 138 and 161). Any site visitor loading an affected documentation page triggers the payload in their browser, enabling session hijacking, credential harvesting, or malicious redirects. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to authenticate to the WordPress site with at minimum a contributor role - confirmed by CVSS PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.4 Medium rating reflects a network-accessible, low-complexity attack requiring low privileges (contributor role, PR:L) with changed scope - appropriate for stored XSS that executes cross-context in victim browsers. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who holds or acquires contributor-level credentials on a target WordPress site opens the block editor, inserts a weDocs Sidebar block on a documentation page, and sets the 'connectorWidth' attribute to a crafted value containing a JavaScript payload (e.g., an event handler or script tag). Upon publishing, the payload is stored in the WordPress database and rendered verbatim by render.php on every subsequent page load, executing in the browsers of all visitors - authenticated or not - who access the affected page. … |
| Remediation | Update the weDocs plugin to the version released after 2.3.0 that incorporates changeset 3589430 from the WordPress plugin SVN repository (https://plugins.trac.wordpress.org/changeset?reponame=&old=3589430%40wedocs&new=3589430%40wedocs); the exact patched release version number is not independently confirmed from available data and should be verified via the WordPress plugin page or the Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/11d68c98-3d7e-42af-be61-6bb5428b73b6. … Detailed patch versions, workarounds, and compensating controls in full report. |
