## Summary

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- barn2media Posts Table with Search & Sort: through 1.4.14

## Description

The Posts Table with Search & Sort plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'date_format' parameter in all versions up to, and including, 1.4.14 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. The payload bypasses wp_kses_post at save time because it contains no literal angle bracket characters; the malicious HTML tags are only reconstructed at render time, making this exploitable by Contributors who would ordinarily lack the unfiltered_html capability.
