CVE-2026-1824: Infomaniak Connect for OpenID <= 1.0.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes

The Infomaniak Connect for OpenID plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'endpoint_login' parameter of the infomaniak_connect_generic_auth_url shortcode in all versions up to, and including, 1.0.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Security readout for executives and security teams

Plain-English summary

CVE-2026-1824 affects the Infomaniak Connect for OpenID WordPress plugin through version 1.0.2. A logged-in user with Contributor-level access or higher can store script content in a shortcode attribute. That script may run when someone views the affected page, creating account and content-tampering risk.

Executive priority

Treat as a near-term website security task, not an emergency. Prioritize sites with many content contributors, weak account controls, or high-value administrator sessions. No active exploitation is shown in the provided sources.

Technical view

The issue is stored cross-site scripting in the infomaniak_connect_generic_auth_url shortcode’s endpoint_login parameter. Sources attribute it to insufficient input sanitization and output escaping. CVSS is 6.4, medium, with low privilege required, network attack vector, changed scope, and low confidentiality and integrity impact.

Likely exposure

Exposure is limited to WordPress sites using Infomaniak Connect for OpenID versions up to and including 1.0.2, where Contributor or higher accounts are available or could be compromised.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Abuse requires authenticated WordPress access at Contributor level or above, then relies on a user viewing affected content.

Researcher notes

Evidence comes from the CVE description, Wordfence entry, and WordPress plugin Trac code references. The provided bundle names vulnerable versions but does not identify a fixed version. Validate against current plugin repository metadata before closing remediation.

Mitigation direction

  • Check the plugin vendor or WordPress plugin page for a fixed release or official guidance.
  • Update the plugin if a newer, vendor-approved version is available.
  • Restrict Contributor-level access to trusted users until remediation is confirmed.
  • Review and remove suspicious uses of the affected shortcode parameter.
  • Temporarily disable the plugin if business risk outweighs authentication functionality.

Validation and detection

  • Inventory WordPress sites for Infomaniak Connect for OpenID installations.
  • Confirm whether installed versions are 1.0.2 or earlier.
  • Review pages and posts containing the affected shortcode.
  • Audit recent edits by Contributor, Author, Editor, and Administrator accounts.
  • Monitor vendor advisories for confirmation of patched versions.
