CVE-2021-47800: b2evolution 7.2.2 - 'edit account details' Cross-Site Request Forgery (CSRF)

b2evolution 7.2.2 contains a cross-site request forgery vulnerability that allows attackers to modify admin account details without authentication. Attackers can craft a malicious HTML form to submit unauthorized changes to user profiles by tricking victims into loading a specially crafted webpage.

Security readout for executives and security teams

Plain-English summary

CVE-2021-47800 affects b2evolution 7.2.2. A malicious webpage could cause a signed-in administrator’s browser to submit unwanted account-detail changes. This is not listed as actively exploited in KEV, but a public ExploitDB reference exists. Business risk is mainly unauthorized admin profile modification if an administrator is tricked into visiting attacker-controlled content.

Executive priority

Treat as a targeted integrity risk, not a broad emergency. Prioritize if b2evolution 7.2.2 supports public-facing or business-critical publishing workflows. Remediate through vendor-supported updates or compensating access controls after confirming exposure.

Technical view

The issue is CWE-352 cross-site request forgery in the “edit account details” function of b2evolution 7.2.2. The CVSS 4.0 score is 6.9, with network access, low complexity, no attacker privileges, and required user interaction. Sources indicate high integrity impact, not confidentiality or availability impact.

Likely exposure

Exposure is limited to organizations running b2evolution 7.2.2, especially internet-facing admin panels or environments where administrators browse untrusted links while authenticated. No other affected versions are identified in the provided sources.

Exploitation context

A public ExploitDB entry exists, so defenders should assume technical details are available. However, the provided sources do not show CISA KEV listing or confirmed active exploitation. Successful abuse requires user interaction by a privileged, authenticated victim.

Researcher notes

The source bundle names only b2evolution 7.2.2 as affected and does not identify a fixed version. Avoid expanding scope without vendor confirmation. The ExploitDB reference supports public exploit availability, but not confirmed real-world exploitation.

Mitigation direction

  • Identify and prioritize any b2evolution 7.2.2 deployments.
  • Check b2evolution vendor guidance and downloads for a supported fixed release.
  • Restrict administrative access to trusted networks where feasible.
  • Ensure administrative actions use CSRF protections and session-hardening controls.
  • Train administrators not to browse untrusted links while logged in.

Validation and detection

  • Confirm installed b2evolution versions across web assets.
  • Review whether admin account-detail changes require valid anti-CSRF tokens.
  • Audit recent admin profile changes for unexpected modifications.
  • Check web logs for unusual account-detail update requests.
  • Verify administrative interfaces are not unnecessarily internet-exposed.
