CVE-2026-1931: Rent Fetch <= 0.32.4 - Unauthenticated Stored Cross-Site Scripting via 'keyword' Parameter

The Rent Fetch plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'keyword' parameter in all versions up to, and including, 0.32.4 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Security readout for executives and security teams

Plain-English summary

CVE-2026-1931 affects the Rent Fetch WordPress plugin through version 0.32.4. An unauthenticated attacker can store malicious JavaScript through the plugin’s keyword handling, causing script execution when affected pages are viewed. This can enable session theft, content manipulation, or user redirection depending on site context.

Executive priority

Prioritize remediation for public WordPress sites using Rent Fetch. The vulnerability is high severity and unauthenticated, so exposure can exist without compromised credentials. If the plugin supports business-critical rental listings, coordinate updates carefully but avoid leaving vulnerable versions online.

Technical view

The issue is stored cross-site scripting in Rent Fetch via the keyword parameter, caused by insufficient input sanitization and output escaping. It is tracked as CWE-79 with CVSS 3.1 score 7.2. The CVE states no authentication is required and scripts execute when users access injected pages.

Likely exposure

WordPress sites running Rent Fetch versions up to and including 0.32.4 are potentially exposed. Public internet-facing WordPress sites are the main concern because the issue is unauthenticated. The source bundle does not identify affected hosted services beyond the WordPress plugin.

Exploitation context

The CVE record and Wordfence entry describe unauthenticated stored XSS. CISA KEV status is false in the provided bundle, and no cited source states active exploitation. Treat as internet-exploitable, but do not assume known in-the-wild exploitation from these sources.

Researcher notes

Evidence supports stored XSS through keyword in Rent Fetch <=0.32.4. The bundle includes code references, a GitHub commit, and a WordPress changeset, but does not clearly name a fixed release version. Avoid claiming active exploitation unless new KEV or vendor intelligence appears.

Mitigation direction

  • Inventory WordPress sites for the Rent Fetch plugin.
  • Identify any Rent Fetch installation at version 0.32.4 or earlier.
  • Update to a vendor release containing the referenced fix when available.
  • If no fixed release is available, consider disabling or removing the plugin.
  • Review vendor, WordPress.org, and Wordfence guidance for current remediation status.

Validation and detection

  • Confirm installed Rent Fetch versions across WordPress environments.
  • Check whether deployed code includes the referenced GitHub commit or WordPress changeset.
  • Review Rent Fetch pages for unexpected stored scripts or unauthorized content changes.
  • Monitor WordPress and web logs for suspicious requests involving the keyword parameter.
  • Re-scan after updating, disabling, or removing the plugin.
