CVE-2026-43625: Cleartext Transmission of Sensitive Information in steipete CodexBar
CodexBar prior to 0.32.0 contains a session cookie leakage vulnerability that allows network attackers to intercept imported browser session cookies by exploiting improper redirect handling for Amp and Ollama provider sessions. Attackers can position themselves on the network path to receive cleartext HTTP requests carrying imported session cookies when a provider-controlled redirect target issues a redirect to a cleartext HTTP endpoint within the same provider domain.
AI Analysis
Technical Summary
CVE-2026-43625 affects steipete CodexBar versions before 0.32.0. The vulnerability involves leakage of session cookies in cleartext during imported browser sessions. This occurs because redirects from Amp and Ollama provider sessions can lead to cleartext HTTP endpoints within the same provider domain, allowing network attackers to intercept session cookies by monitoring HTTP traffic. The issue is due to improper handling of redirects that do not enforce secure transmission (HTTPS), exposing sensitive session data to interception.
Potential Impact
An attacker who can position themselves on the network path between the user and the CodexBar service can intercept session cookies transmitted in cleartext HTTP requests. This compromises session confidentiality and could enable session hijacking or unauthorized access to user sessions. The vulnerability does not require user interaction and has a high severity score (CVSS 8.2), indicating significant risk if exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should avoid using affected versions prior to 0.32.0 in untrusted network environments. Network-level protections such as enforcing HTTPS and avoiding redirects to cleartext HTTP endpoints within the same domain may reduce exposure.
