By repeatedly initiating the OAuth2 login flow without completing it, attackers can force the server to allocate state variables in an unbounded in-memory map. This heap-based resource exhaustion eventually causes the host operating system to terminate the OliveTin process via the Out-Of-Memory (OOM) killer.\n\n## TL;DR\nUnauthenticated remote attackers can exhaust OliveTin server memory and crash the application by flooding the OAuth2 login endpoint, forcing unbounded allocation of state variables in memory.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-400\n- **Attack Vector**: Network\n- **CVSS v3.1**: 7.5\n- **EPSS Score**: 0.00354\n- **Impact**: Denial of Service (DoS)\n- **Exploit Status**: PoC (Proof-of-Concept)\n- **KEV Status**: Not listed\n\n## Affected Systems\n\n- OliveTin\n- **OliveTin**: >= 3000.0.0, < 3000.17.0 (Fixed in: `3000.17.0`)\n\n## Mitigation\n\n- Upgrade to OliveTin 3000.17.0 or later\n- Implement rate-limiting on the /oauth/login route via a reverse proxy (e.g., Nginx)\n- Restrict access to the OliveTin interface using firewall rules or VPNs\n\n**Remediation Steps:**\n1. Identify running versions of OliveTin using asset management or container manifests.\n2. Deploy the 3000.17.0 update across affected environments.\n3. Configure reverse proxies to limit HTTP requests to /oauth/login to prevent resource exhaustion or service unavailability.\n\n## References\n\n- [GHSA-xpxj-f2fm-rqch: OliveTin OAuth2 state memory exhaustion advisory](https://github.com/OliveTin/OliveTin/security/advisories/GHSA-xpxj-f2fm-rqch)\n- [NVD Entry for CVE-2026-67437](https://nvd.nist.gov/vuln/detail/CVE-2026-67437)\n- [CVE.org Record for CVE-2026-67437](https://www.cve.org/CVERecord?id=CVE-2026-67437)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-67437) -
