Short explanation
Traefik before versions 2.11.58 and 3.7.14 contains a race condition in NTLM and Kerberos backend authentication. Remote attackers can send concurrent requests over a single connection to orphan backend connections, break connection-bound authentication, or crash Traefik.
This vulnerability can impact application availability by disrupting authentication integrity or causing denial of service. Discrepancies exist between sources regarding metrics; S1 records a CVSS base score of 6.3 (MEDIUM) while NVD reports 3.7 (LOW).
What should be done?
- Follow vendor advisory guidance
- Keep Traefik deployments updated
- Monitor for updates regarding vendor patches

Chain of evidence and sources
Traefik 2.11.x sürümleri (2.11.58 öncesi) ve 3.x sürümleri (3.7.14 öncesi), NTLM ve Kerberos arka uç kimlik doğrulamasında bir yarış koşulu içerir.
Saldırganlar tek bir bağlantı üzerinden eşzamanlı HTTP/2 veya HTTP/3 istekleri göndererek arka uç bağlantılarını yetim bırakabilir, kimlik doğrulamasını bozabilir veya Traefik'i çökletebilir.
Kaynaklar arasında CVSS skoru konusunda uyuşmazlık bulunmakta olup, S1 kaynaklı veri CVSS tabanlı puanı 6.3 (MEDIUM) olarak verirken NVD 3.7 (LOW) bildirmektedir.
Show the technical text from the sources
Traefik 2.11.x before 2.11.58 and 3.x before 3.7.14 contains a race condition in NTLM and Kerberos (Negotiate) backend authentication, where the per-connection sticky round tripper slot is read and written without synchronization. Remote attackers can send concurrent HTTP/2 or HTTP/3 requests over one connection to orphan backend connections, break connection-bound authentication, or crash Traefik.
