MEDIUM 4.3

DescriptionCVE.org

The Company Posts for LinkedIn plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.0.0. This is due to a missing capability check on the linkedin_company_post_reset_handler() function hooked to admin_post_reset_linkedin_company_post. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete LinkedIn post data stored in the site's options table.

AnalysisAI

The Company Posts for LinkedIn WordPress plugin (versions up to 1.0.0) contains a missing authorization vulnerability in the linkedin_company_post_reset_handler() function that allows authenticated attackers with Subscriber-level privileges to delete LinkedIn post data from the site's options table without proper capability checks. This is a privilege escalation flaw where low-privileged users can perform administrative actions. While the CVSS score is moderate at 4.3 and reflects limited integrity impact without confidentiality or availability concerns, the vulnerability enables unauthorized modification of site configuration data by any authenticated user.

Technical ContextAI

The vulnerability exists in the WordPress plugin architecture where admin-post actions are improperly protected. The affected plugin (cpe:2.3:a:brainstation23:company_posts_for_linkedin:*:*:*:*:*:*:*:*) registers a handler to the admin_post_reset_linkedin_company_post action without implementing WordPress capability checks (such as current_user_can() with appropriate administrator or manage_options capabilities). This represents a CWE-862 (Missing Authorization) vulnerability class where access control validation is completely absent. The plugin hooks directly into WordPress's admin-post action system which, by design, fires for both authenticated and unauthenticated requests, making the missing check particularly dangerous since any logged-in user—even with minimal Subscriber role—can trigger destructive operations on site options.

RemediationAI

Update the Company Posts for LinkedIn plugin to a version beyond 1.0.0 that includes proper capability checks (the plugin vendor should release a patched version implementing current_user_can('manage_options') or appropriate equivalent checks on the linkedin_company_post_reset_handler() function). If immediate patching is unavailable, disable the plugin entirely until a security update is released, as there are limited server-side workarounds for application-level authorization flaws. Additionally, enforce principle of least privilege by restricting WordPress user registration to trusted administrators and regularly audit user roles to ensure Subscriber-level accounts are not unnecessarily granted to untrusted parties.
