Security readout for executives and security teams
Plain-English summary
A WordPress plugin used for daily prayer times can store malicious script content when used by an authenticated contributor or higher. If another user views the affected content, the script may run in their browser. This is not marked as known exploited, but it matters for sites with many content users.
Executive priority
Treat as a moderate-priority website risk. Prioritize internet-facing WordPress sites, community-managed content workflows, and environments where contributor accounts are common. This is less urgent than unauthenticated remote code execution but should not remain unresolved on public sites.
Technical view
CVE-2023-27631 is an authenticated stored XSS issue in mmrs151 Daily Prayer Time for Mosques plugin versions up to 2023.05.04. It is CWE-79 with CVSS 3.1 score 6.5: AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L. The bundle does not provide the exact sink or fixed version.
Likely exposure
Exposure is limited to WordPress sites running the Daily Prayer Time plugin at version 2023.05.04 or earlier, especially where contributor-level accounts are granted to untrusted or lightly governed users.
Exploitation context
The sources do not report active exploitation, and CISA KEV status is false. Exploitation requires authenticated contributor-level access or higher and victim interaction. Stored XSS can affect confidentiality, integrity, and availability at a limited level in the victim browser context.
Researcher notes
Evidence is thin beyond the CVE and Patchstack entry. The source bundle names authenticated stored XSS but does not include vulnerable parameters, proof of concept, exploit telemetry, or a confirmed fixed version. Avoid assuming active exploitation or a specific patch level without vendor confirmation.
Mitigation direction
- Inventory WordPress sites for the Daily Prayer Time plugin.
- Check vendor, WordPress, or Patchstack guidance for a fixed release.
- Update to a vendor-supported fixed version if one is available.
- Disable or remove the plugin if no maintained fixed version exists.
- Restrict contributor-level access to trusted users pending remediation.
Validation and detection
- Confirm plugin presence and exact version across WordPress assets.
- Review whether contributor or higher accounts are broadly assigned.
- Check vendor or Patchstack records for fixed-version availability.
- Retest affected pages after remediation using safe XSS validation methods.

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.
