Unauthenticated AJAX Actions Enable Arbitrary Post Creation

The Tablesome Table WordPress plugin before 1.1.31 does not perform any authentication, capability, or nonce checks in one of its AJAX actions, allowing unauthenticated users to create new published posts and to overwrite arbitrary existing posts and pages.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

The Tablesome Table WordPress plugin before version 1.1.31 contains a critical authentication bypass vulnerability in its AJAX handlers. By failing to implement proper authentication, capability, and nonce verification checks, the plugin allows unauthenticated attackers to execute privileged actions remotely. This vulnerability enables threat actors to create new published posts and overwrite existing posts and pages on affected WordPress installations without any valid credentials. Organizations running vulnerable versions of this widely-used plugin face immediate risk of content manipulation, malware injection, and reputation damage, with the attack requiring no special tools or exploit code—only direct HTTP requests to the vulnerable AJAX endpoints.

Using Claude AI with extended reasoning across 283 mapped security skills, Casky detects the attack patterns underlying this vulnerability by analyzing two critical MITRE ATT&CK techniques: TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky would observe findings related to unauthorized privilege escalation through missing access controls (CWE-862), coupled with patterns of unauthenticated request handling that bypass standard WordPress nonce and capability checks. The platform's skill mappings would surface detection patterns for suspicious AJAX requests originating from unauthenticated sessions, unexpected post creation or modification activities, and anomalous administrative actions lacking proper authentication tokens—enabling security teams to identify exploitation attempts in logs and web traffic before posts are maliciously created or overwritten.
