tagDiv Opt-In Builder: SQL injection in td-subscription plugin
Summary
The tagDiv Opt-In Builder WordPress plugin (td-subscription component), versions up to and including 1.7.6, contains a blind SQL injection flaw. An attacker can send crafted requests to the plugin to read, modify or delete data in the WordPress database, including user accounts. The CVSS score of 8.5 assumes that low-privilege access is required, but a related record (CVE-2026-96330) for the same plugin and fix version claims unauthenticated exploitation, so the actual exposure may be higher.
Affected
- tagDiv Opt-In Builder WordPress plugin, versions up to and including 1.7.6
- Version range wording differs by source: 'from n/a through 1.7.6' (CVE record) and '<1.7.7' (aggregator)
- Required privilege: Low (CVSS vector PR:L) per this CVE; Unauthenticated per Patchstack's listing for CVE-2026-96330 (unresolved)
Fixed in
- Version 1.7.7 or later (per Patchstack; not yet confirmed in the vendor changelog)
Workaround
- No vendor-published workaround found.
- Patchstack advises updating the plugin; if this is not possible, ask your hosting provider or web developer for help.
- Patchstack has issued a mitigation rule (virtual patch) for this issue.
Exploitation
- In the wild: no confirmed evidence. Patchstack expects exploitation, which is a prediction.
- CISA SSVC: exploitation none, automatable no, technical impact partial.
- Not listed as KEV (per Strix).
- Public proof of concept: none found for this CVE.
Our recommendation
- Update the plugin to version 1.7.7 or later on every WordPress site, and confirm the installed version afterwards.
- Verify the fix against the vendor changelog, since 1.7.7 is not yet vendor-confirmed.
- If the plugin is not essential, deactivate it.
- Restrict access to its endpoints and use a WAF or virtual patching until the update is done.
- Check the database and user accounts for signs of compromise, especially on public sites with user registration enabled.
- Treat the issue as high priority until the relationship with CVE-2026-96330 is clarified.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
