CVE-2021-24549: AceIDE <= 2.6.2 - Authenticated (admin+) Arbitrary File Access

The AceIDE WordPress plugin through 2.6.2 does not sanitise or validate the user input which is appended to system paths before using it in various actions, such as to read arbitrary files from the server. This allows high privilege users such as administrator to access any file on the web server outside of the blog directory via a path traversal attack.

Security readout for executives and security teams

Plain-English summary

AceIDE for WordPress through version 2.6.2 can let an authenticated administrator read files outside the WordPress blog directory. The business risk is exposure of sensitive server files, but the sources indicate the attacker already needs high-privilege access.

Executive priority

Treat this as a focused WordPress hardening item, not an internet-wide emergency. Prioritize sites where AceIDE is installed and admin accounts are exposed, shared, or weakly protected.

Technical view

The plugin appends unsanitized user input to system paths in file-related actions, creating CWE-22 path traversal. Sources describe arbitrary file read on the web server by authenticated admin-level users. No CVSS, CPE, or vendor remediation detail is provided in the bundle.

Likely exposure

Exposure is likely limited to WordPress sites running AceIDE through 2.6.2 where an administrator account is compromised, malicious, or shared too broadly.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation. Public references describe the vulnerability class and admin-authenticated file access, but not confirmed exploitation in the wild.

Researcher notes

Evidence supports authenticated admin-level arbitrary file read via path traversal. The bundle lacks CVSS, CPEs, exploit status, and definitive patch information, so remediation should be confirmed against vendor or WPScan data.

Mitigation direction

  • Inventory WordPress sites for AceIDE and confirm installed versions.
  • Remove AceIDE if it is not operationally required.
  • Check vendor or WPScan guidance for any maintained fixed version.
  • Restrict WordPress administrator access to trusted users only.
  • If exposure is suspected, review potentially readable secrets and incident response needs.

Validation and detection

  • Confirm whether AceIDE version 2.6.2 or earlier is installed.
  • Review administrator account access, MFA status, and recent account changes.
  • Check web and WordPress logs for unusual AceIDE file-access activity.
  • Confirm the plugin is removed or updated according to vendor guidance.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
