CVE-2026-49135: Insecure Temporary File in steipete CodexBar
CodexBar prior to 0.32.0 contains an insecure temporary file handling vulnerability that allows local attackers to access sensitive credentials or tamper with build artifacts by exploiting predictable file paths in the release notarization workflow. Attackers with access to the same host can read the App Store Connect API key written to a fixed path, pre-create files or symbolic links at predictable locations to redirect writes to attacker-controlled destinations, or tamper with notarization archives before submission.
AI Analysis
Technical Summary
CVE-2026-49135 describes a vulnerability in steipete's CodexBar before version 0.32.0 where insecure handling of temporary files in the release notarization workflow allows local attackers to exploit predictable file paths. Attackers can read sensitive credentials such as the App Store Connect API key stored at fixed paths, pre-create files or symbolic links to redirect writes to attacker-controlled locations, or tamper with notarization archives prior to submission. The vulnerability requires local access with low privileges and does not involve user interaction. It has a CVSS 4.0 score of 7.2, indicating high severity.
Potential Impact
Local attackers with access to the same host can read sensitive credentials (App Store Connect API key) and tamper with build artifacts or notarization archives. This can compromise the integrity of the build and release process and expose sensitive API keys, potentially leading to unauthorized access or manipulation of the software distribution pipeline.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch link is provided, users should monitor the vendor's announcements for updates. In the meantime, restrict local access to trusted users only and avoid running the vulnerable versions on shared or untrusted hosts to reduce risk.
