# Safe Codex Prompt: CVE-2026-11354

Prepare a defensive remediation plan for CVE-2026-11354.

Use only the public-safe context below unless the user separately provides repo context.

Source summary: NVD: The Participants Database plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.7.8.3 via the 'id' parameter. NVD: This makes it possible for unauthenticated attackers to overwrite arbitrary participant records by numeric ID and redirect the private_id-bearing record-access link to an attacker-controlled email address, granting full read and edit access to the victim's... NVD: An attacker can harvest a valid nonce with a plain unauthenticated GET request to any page rendering the public signup or record form, then POST action=update with an arbitrary id value to overwrite any record; chaining a subsequent action=retrieve then...
Affected vendor/product: unknown / unknown
Risk context: {'severity': 'MEDIUM', 'cvss_score': 5.3, 'cvss_label': 'MEDIUM', 'epss_percentile': 0.15181, 'kev_status': 'not_listed', 'risk_flags': ['official reference present']}
Remediation context: {'recommended_route': 'vendor_patch_or_mitigation', 'reference_status': 'official_reference_present', 'patch_status': 'requires_confirmation', 'fixed_versions': [], 'mitigation_notes': ['Remediation reference present; patch status requires confirmation in the linked advisory.', 'Patch status requires confirmation from the linked advisory or official source.']}
