curl 7.63.0 to and including 7.75.0 includes vulnerability that allows a malicious HTTPS proxy to MITM a connection due to bad handling of TLS 1.3 session tickets. When using a HTTPS proxy and TLS 1.3, libcurl can confuse session tickets arriving from the HTTPS proxy but work as if they arrived...

OAuth2-Proxy is vulnerable to header smuggling via underscore leading to potential privilege escalation

Impact All deployments of OAuth2 Proxy in front of applications that normalize underscores to dashes in HTTP headers e.g., WSGI-based frameworks such as Django, Flask, FastAPI, and PHP applications. Authenticated users can inject underscore variants of X-Forwarded- headers that bypass the proxy’s...

python-kdcproxy: Remote DoS via unbounded TCP upstream buffering

If an attacker causes kdcproxy to connect to an attacker-controlled KDC server e.g. through server-side request forgery, they can exploit the fact that kdcproxy does not enforce bounds on TCP response length to conduct a denial-of-service attack. While receiving the KDC's response, kdcproxy copie...

CVE-2025-59089

If an attacker causes kdcproxy to connect to an attacker-controlled KDC server e.g. through server-side request forgery, they can exploit the fact that kdcproxy does not enforce bounds on TCP response length to conduct a denial-of-service attack. While receiving the KDC's response, kdcproxy copie...

CVE-2025-59088

If kdcproxy receives a request for a realm which does not have server addresses defined in its configuration, by default, it will query SRV records in the DNS zone matching the requested realm name. This creates a server-side request forgery vulnerability, since an attacker could send a request f...

CVE-2025-64484

A header-smuggling vulnerability was found in OAuth2-Proxy’s handling of HTTP headers containing underscores such as XForwardedFor. The proxy failed to properly normalize these header names, which could allow crafted requests to bypass header validation or filtering. When OAuth2-Proxy is deployed...
