Security readout for executives and security teams
Plain-English summary
CVE-2026-24536 is a medium-severity information exposure issue in the WordPress Webpushr plugin through version 4.38.0. An unauthenticated remote attacker may be able to retrieve embedded sensitive data. The available sources do not identify active exploitation or a specific fixed version.
Executive priority
Treat this as a moderate-priority WordPress exposure issue. It does not currently show known exploited status, but unauthenticated access and potential sensitive data disclosure justify prompt inventory and remediation planning, especially for public marketing or customer-facing sites.
Technical view
The CVE describes CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere in webpushr-web-push-notifications. CVSS 3.1 is 5.3, with network access, low complexity, no privileges, and no user interaction required. Impact is limited to confidentiality; integrity and availability are not affected in the CVSS vector.
Likely exposure
Exposure is likely limited to WordPress sites running the Webpushr plugin at version 4.38.0 or earlier. Public sources do not provide more detail on the exposed data type, affected endpoint, or environmental prerequisites.
Exploitation context
The CVSS vector indicates unauthenticated network exploitability with low complexity. The source bundle shows this CVE is not in CISA KEV, and no cited source claims active exploitation. Do not treat it as actively exploited based on current evidence.
Researcher notes
Public detail is limited. The record identifies sensitive information exposure but does not describe the vulnerable component, data exposed, proof-of-concept status, or fixed release. Avoid assumptions beyond Webpushr plugin versions through 4.38.0 and the CVSS/CWE data provided.
Mitigation direction
- Inventory WordPress sites for the Webpushr plugin.
- Identify installations running Webpushr version 4.38.0 or earlier.
- Check vendor and Patchstack guidance for fixed versions or workarounds.
- Disable or remove the plugin where business use is not required.
- Prioritize remediation for internet-facing WordPress sites.
Validation and detection
- Confirm plugin name: webpushr-web-push-notifications.
- Record installed Webpushr versions across WordPress assets.
- Flag any active installation at version 4.38.0 or earlier.
- Review public vendor or Patchstack pages for updated remediation status.
- Monitor web logs for unusual unauthenticated requests to plugin-related paths.
