Deserialization Of Untrusted Data

c3p0 is vulnerable to Deserialization of Untrusted Data. The vulnerability is due to the use of DataSource and ConnectionPoolDataSource objects that can participate in Java deserialization gadget chains, which allows an attacker to trigger arbitrary code execution when malicious serialized object...

undici: undici: Information disclosure and data integrity issues due to incorrect Socks5ProxyAgent connection routing

A flaw was found in undici. When using Socks5ProxyAgent, undici incorrectly reuses a single connection pool across different origins. This can lead to cross-origin request routing, where sensitive credentials and data intended for one destination are sent to another. Consequently, responses from...

SUSE CVE-2026-11564

libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. An easy handle that first uses default native CA trust can continue trusting the native platform store after the application switches that same handle to custom CA...

CVE-2026-11564

A flaw was found in curl. When libcurl reuses a connection from its connection pool, an easy handle that initially used default native Certificate Authority CA trust may continue to trust the native platform store. This occurs even after the application has switched that same handle to custom CA...

ChatterBot Vulnerable to Denial of Service via Database Connection Pool Exhaustion

SummaryChatterBot versions up to 1.2.10 are vulnerable to a denial-of-service condition caused by improper database session and connection pool management. Concurrent invocations of the getresponse method can exhaust the underlying SQLAlchemy connection pool, resulting in persistent service...

PYSEC-2026-1244 ChatterBot Vulnerable to Denial of Service via Database Connection Pool Exhaustion

Summary ChatterBot versions up to 1.2.10 are vulnerable to a denial-of-service condition caused by improper database session and connection pool management. Concurrent invocations of the getresponse method can exhaust the underlying SQLAlchemy connection pool, resulting in persistent service...

SUSE CVE-2026-6734

Impact: When using Socks5ProxyAgent, undici reuses a single connection pool across different origins without verifying that the pool's origin matches the requested origin. All requests are dispatched through the pool connected to the first origin, regardless of the intended destination. This caus...

PYSEC-2026-1873 Requests `Session` object does not verify requests after making first request with verify=False

When using a requests.Session, if the first request to a given origin is made with verify=False, TLS certificate verification may remain disabled for all subsequent requests to that origin, even if verify=True is explicitly specified later. This occurs because the underlying connection is reused...

Authentication Bypass by Primary Weakness

Overview Affected versions of this package are vulnerable to Authentication Bypass by Primary Weakness in the connection pool process. An attacker can bypass intended certificate validation by reusing a handle that initially used the default native CA trust and then switching it to custom CA...

AZL-91827 CVE-2026-8932 affecting package cmake for versions less than 3.30.3-15

libcurl would reuse a previously created connection even when some mTLS config related option had been changed that should have prohibited reuse. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, some TLS...
