CVE-2023-0178: Annual Archive < 1.6.0 - Contributor+ Stored XSS

The Annual Archive WordPress plugin before 1.6.0 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.

Security readout for executives and security teams

Plain-English summary

CVE-2023-0178 affects the Annual Archive WordPress plugin before 1.6.0. A logged-in user with contributor-level access or higher could store malicious script content through shortcode attributes, causing it to run when another user views the affected page or post.

Executive priority

Treat as a moderate-priority remediation for affected WordPress estates. It is not cited as actively exploited, but stored XSS can affect administrators or visitors and may support account abuse or content tampering if left unresolved.

Technical view

The plugin failed to validate and escape some shortcode attributes before rendering them into page or post output. This is stored cross-site scripting, CWE-79, with CVSS 3.1 score 5.4. Exploitation requires low privileges and user interaction, with changed scope and limited confidentiality and integrity impact.

Likely exposure

Exposure is limited to WordPress sites running Annual Archive before 1.6.0, especially where contributor or higher roles can create or edit posts using the plugin shortcode.

Exploitation context

The source bundle cites WPScan with an exploit tag, but CISA KEV is false and no provided source confirms active exploitation in the wild.

Researcher notes

The public data identifies the vulnerable condition and fixed-version boundary, but vendor attribution and CPE coverage are incomplete in the provided bundle. Validate exposure by plugin presence and version rather than relying on CPE matching alone.

Mitigation direction

  • Upgrade Annual Archive to version 1.6.0 or later.
  • Remove or disable the plugin if it is unnecessary.
  • Restrict contributor-level posting privileges until remediation is complete.
  • Review vendor guidance for any additional hardening advice.
  • Review existing shortcode usage for unsafe or unexpected attributes.

Validation and detection

  • Inventory WordPress sites for the Annual Archive plugin and version.
  • Confirm all instances run version 1.6.0 or later.
  • Identify posts or pages containing Annual Archive shortcodes.
  • Review contributor-authored content for unexpected script-bearing output.
  • Check whether contributor or higher roles are granted only as needed.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
