DescriptionCVE.org

The Job Postings plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'position_button' parameter in all versions up to, and including, 2.8.1 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 Job Postings WordPress plugin (versions ≤ 2.8.1) allows authenticated attackers with contributor-level access to inject persistent JavaScript payloads via the 'position_button' parameter, which subsequently execute in the browsers of any user who views the affected page. The vulnerability stems from insufficient sanitization of input and missing output escaping in class-job-add-edit.php, enabling session hijacking, credential theft, or malicious redirects against visiting users including administrators. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated WordPress user account with contributor-level access or higher on the target installation - unauthenticated remote exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The NVD-assigned CVSS 6.4 base score (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N) accurately reflects the limited confidentiality and integrity impact and the changed scope, but the UI:N metric is debatable: a victim must browse to the page containing the injected payload, which typically warrants UI:R. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Update the Job Postings plugin to a release beyond version 2.8.1 once the plugin developer publishes a patched version to the WordPress plugin repository - no exact patched version number was confirmed in the provided intelligence, so administrators should verify the current plugin repository state before updating. … Detailed patch versions, workarounds, and compensating controls in full report.
