Security readout for executives and security teams
Plain-English summary
CVE-2022-45811 is a missing authorization flaw in the WordPress Post Teaser plugin through 4.1.5. A logged-in user could reach functionality they should not be allowed to use, with limited integrity and availability impact. It is not listed in CISA KEV, and the provided sources do not show active exploitation.
Executive priority
Prioritize in normal vulnerability remediation cycles, faster for WordPress sites with many contributor or subscriber accounts. Business urgency is moderate because exploitation requires authentication and the documented impact is limited, but access-control flaws can still damage content integrity or operations.
Technical view
The CVE record describes CWE-862 Missing Authorization in WeyHan Ng Post Teaser, affecting versions up to 4.1.5. CVSS 3.1 is 5.4: network reachable, low complexity, low privileges required, no user interaction, unchanged scope, low integrity and availability impact, no confidentiality impact.
Likely exposure
Exposure is limited to WordPress sites with the Post Teaser plugin installed at version 4.1.5 or earlier. The CVSS vector requires an authenticated low-privilege account, so public unauthenticated exposure is not supported by the provided evidence.
Exploitation context
The source bundle does not cite exploit code, exploitation in the wild, or CISA KEV listing. Treat this as a plausible authenticated misuse risk rather than confirmed active exploitation.
Researcher notes
The available bundle is sparse: it identifies the vulnerability class, affected plugin and version ceiling, CVSS vector, and Patchstack entry, but not the vulnerable endpoint, fixed version, or vendor advisory text. Do not infer unauthenticated impact or a specific patch without additional vendor evidence.
Mitigation direction
- Inventory WordPress sites for the Post Teaser plugin and record installed versions.
- If running 4.1.5 or earlier, check vendor or Patchstack guidance for a fixed release.
- Disable or remove the plugin where it is unnecessary or no fix is available.
- Limit creation and use of low-privilege WordPress accounts until remediation is confirmed.
- Monitor WordPress audit logs for unexpected plugin-related administrative actions.
Validation and detection
- Confirm whether the post-teaser plugin is installed on each WordPress instance.
- Verify the installed plugin version is newer than the affected range or the plugin is absent.
- Review user roles and remove stale low-privilege accounts that could reach plugin functionality.
- Check vulnerability management records for CVE-2022-45811 tracking and closure evidence.

Missing Authorization
Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
