Security readout for executives and security teams
Plain-English summary
CVE-2026-25031 affects the WordPress Tasty Daily theme before version 1.27. It is rated critical because a remote, unauthenticated attacker may trigger unsafe PHP deserialization, potentially compromising the site’s confidentiality, integrity, and availability. No provided source confirms active exploitation.
Executive priority
Treat as urgent for any public WordPress site using Tasty Daily. The severity is critical and the attack requires no login or user action per CVSS. Patch or remove affected deployments quickly, while noting that active exploitation is not confirmed by the provided sources.
Technical view
The issue is CWE-502 deserialization of untrusted data in park_of_ideas Tasty Daily (tastydaily), affecting versions through <1.27. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, score 9.8. Public detail is limited to the CVE record and Patchstack entry.
Likely exposure
Exposure is likely limited to WordPress sites using the Tasty Daily theme below version 1.27. Internet-facing WordPress sites are the primary concern. The provided data does not identify affected managed hosting platforms, plugins, or non-WordPress products.
Exploitation context
The CVSS vector indicates network reachability, low attack complexity, no privileges, and no user interaction. The source bundle does not include exploit code, proof-of-concept details, or confirmation of exploitation in the wild. It is not listed as KEV in the provided data.
Researcher notes
Evidence is sparse. The CVE entry identifies unsafe deserialization and Patchstack is the only vulnerability database reference in the bundle. No vulnerable parameter, exploit chain, or gadget requirements are provided. Validate exposure through asset inventory rather than assumptions.
Mitigation direction
- Inventory WordPress sites for the Tasty Daily theme.
- Update Tasty Daily to version 1.27 or later if available.
- If unable to update, disable or replace the theme.
- Review Patchstack and vendor guidance for any additional remediation.
- Prioritize internet-facing and business-critical WordPress sites first.
Validation and detection
- Confirm whether Tasty Daily is installed on each WordPress site.
- Record the installed theme version and compare it to 1.27.
- Verify the site is no longer running an affected version.
- Check security monitoring for suspicious WordPress activity.
- Document exceptions where updates or replacement are delayed.
