CVE-2026-121554
cordova-plugin-advanced-http 1.5.0 through 3.3.1 contains an information disclosure vulnerability that leaks cookies to third-party hosts because the JavaScript layer passes jar-built Cookie headers as ordinary request headers. When a request is redirected to another host via an open or attacker-influenced redirect, native iOS and Android stacks forward the Cookie header, letting attackers hijack user sessions.

Affected products and versions
NVD has not supplied machine-readable vulnerable CPE product/version entries for this CVE. This is an information gap, not proof that no products are affected. Check the vendor advisory references below.
Remediation & validation
- Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
- Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
- Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
- Validate the remediation with a version check and vulnerability rescan, then retain change evidence.
No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
