CVE-2023-0360: Location Weather < 1.3.4 - Contributor+ Stored XSS

The Location Weather WordPress plugin before 1.3.4 does not validate and escape some of its block options before outputting them back in a page/post where the block 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-2023-0360 is a stored cross-site scripting issue in the Location Weather WordPress plugin before 1.3.4. A Contributor-level user or higher could save unsafe block options that execute when someone views the affected page or post. This mainly matters where lower-privileged authors can publish or submit content.

Executive priority

Prioritize remediation on WordPress sites with multiple content contributors or external authors. The severity is moderate, but stored XSS can affect visitors and administrators who view compromised content. Single-admin sites with no untrusted authors have lower practical exposure.

Technical view

The plugin failed to validate and escape some block options before rendering them in embedded blocks. The issue is CWE-79 with CVSS 3.1 score 5.4: network reachable, low complexity, low privileges required, user interaction required, changed scope, low confidentiality and integrity impact, no availability impact.

Likely exposure

Exposure is likely limited to WordPress sites running Location Weather before 1.3.4, especially sites with Contributor, Author, Editor, or Administrator accounts beyond fully trusted staff. The source bundle has sparse structured affected-version metadata, but the description identifies versions before 1.3.4.

Exploitation context

WPScan lists a public vulnerability entry tagged as exploit and technical description. The source bundle does not show CISA KEV status or cited evidence of active exploitation. Treat this as a credible stored XSS risk, not confirmed in-the-wild exploitation.

Researcher notes

Focus validation on block option handling and output encoding in Location Weather blocks. Do not assume broader product impact beyond the named plugin and versions before 1.3.4. Evidence does not support claiming active exploitation.

Mitigation direction

  • Upgrade Location Weather to version 1.3.4 or later.
  • Restrict Contributor-level access to trusted users only.
  • Review posts and pages containing Location Weather blocks.
  • Remove suspicious script-like content from affected block options.
  • Check vendor and WordPress plugin guidance for any additional fixes.

Validation and detection

  • Inventory WordPress sites using the Location Weather plugin.
  • Confirm installed plugin versions are 1.3.4 or later.
  • Review user roles with Contributor access or higher.
  • Search affected content for unusual block option values.
  • Verify rendered pages encode block option output safely.
