ThemeREX Dwell theme: PHP object injection via untrusted data deserialization
Summary
The WordPress theme Dwell up to and including version 1.16.0 deserializes untrusted data, which allows PHP object injection. An unauthenticated remote attacker can send crafted requests to a public website, which may enable code execution, data access or disruption of the site, depending on the PHP gadget chains present. Patchstack rates the issue as high priority and expects exploitation, but no known exploitation exists yet.
Affected
- Dwell WordPress theme, all versions up to and including 1.16.0
- Vendor naming is somewhat unclear: ThemeREX Group and AxiomThemes are both linked to the theme
Fixed in
- Unknown. No official patch has been confirmed by Patchstack or the sources reviewed.
- Releases 1.17.0, 1.18.0 and 1.19.0 exist, but their changelogs do not mention this CVE. Verify the fix before relying on it.
Workaround
- No vendor workaround found.
- Ask the hosting provider or web developer for help if the theme cannot be updated.
- Restrict or take affected sites offline until a fix is verified.
- A WAF virtual patch may help; confirm the rule with Patchstack or the WAF vendor first.
Exploitation
- No known exploitation; CISA SSVC lists exploitation as none and automatable as yes.
- No public proof of concept found.
- Patchstack states such flaws are expected to be exploited and used in mass-exploit campaigns.
Our recommendation
- Inventory all WordPress sites and check for the Dwell theme and its version.
- Update to the latest release, then verify with the vendor that the fix is included.
- If a site is internet-facing and cannot be updated, restrict or disable it or add a WAF virtual patch.
- Check ThemeREX Addons (TrxAddons) components and update CVE-2026-62105 fixes (version 2.45.0) where used.
- Review logs for unusual requests and check file integrity.
- Monitor NVD and Patchstack, as the NVD status is still Deferred.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
