axiomthemes Redy: PHP object injection via untrusted data
Summary
The axiomthemes Redy WordPress theme up to and including version 1.3.5 deserializes untrusted data (CWE-502), which allows PHP object injection. According to the CNA record, an unauthenticated attacker can send a crafted request over the network without user interaction. Successful exploitation could affect confidentiality, integrity and availability, and possibly lead to code execution, depending on the PHP classes available on the target site.
Affected
- Redy WordPress theme, versions up to and including 1.3.5
- Earlier versions: lower bound unknown (listed as 'n/a')
Fixed in
Unknown. Patchstack reports no official patch available. Check the vendor's site and theme changelog before assuming any version is safe.
Workaround
- No vendor workaround known.
- Virtual patching or a web application firewall that blocks the vulnerable entry points (for example Patchstack mitigation rules).
- Restrict access to the admin area and check for unexpected files or admin accounts.
- Take a verified backup before any change.
Exploitation
- Exploitation status: not confirmed as known exploited (KEV/ITW).
- Patchstack expects exploitation but describes this as a prediction, not an observed attack.
- No public proof-of-concept found in the sources checked.
- VDB rates exploitation as easy.
Our recommendation
- Identify every site running Redy, including staging copies.
- Remove the theme or move to a maintained theme if possible.
- If the theme must remain, apply virtual patching and restrict access.
- Monitor for a vendor fix and recheck the Patchstack and NVD pages.
- Review logs and site files for signs of compromise.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
