Security readout for executives and security teams
Plain-English summary
CVE-2022-45077 affects WordPress sites using the Betheme theme version 26.5.1.4 or older. A logged-in user with subscriber-level access or higher may trigger PHP object injection, potentially affecting confidentiality, integrity, and availability at a limited level.
Executive priority
Treat as a medium-priority WordPress exposure issue. Prioritize internet-facing sites using Betheme with public registration or many low-privilege accounts, then update through normal change control once vendor guidance is confirmed.
Technical view
The issue is CWE-502 deserialization/PHP object injection in Muffingroup Betheme for WordPress <= 26.5.1.4. CVSS 3.1 is 6.3, network reachable, low complexity, low privileges required, no user interaction, unchanged scope, and low CIA impact.
Likely exposure
Exposure is limited to WordPress installations running Betheme <= 26.5.1.4 where an attacker can authenticate as subscriber or higher. Sites with open registration, many low-privilege users, or weak account controls have higher practical risk.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires authenticated access. Real impact may depend on application state and available PHP object paths, which are not detailed in the sources.
Researcher notes
Evidence is narrow: affected product/version, CWE, CVSS, and authenticated requirement are provided, but no CPEs, exploit evidence, or fixed version are included in the bundle. Avoid assuming unauthenticated exposure or confirmed in-the-wild exploitation.
Mitigation direction
- Inventory WordPress sites using Muffingroup Betheme.
- Check Betheme versions and flag 26.5.1.4 or older.
- Consult Muffingroup or Patchstack guidance for the fixed release.
- Update Betheme if a vendor-supported fixed version is available.
- Restrict public registration and audit low-privilege accounts.
Validation and detection
- Confirm installed Betheme version on each WordPress site.
- Verify whether subscriber-level accounts can be self-registered.
- Review Patchstack and vendor advisories for fixed-version details.
- Check WordPress logs for suspicious authenticated activity.
- Confirm remediation by rechecking theme version after update.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
