Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the TLS handshake process. An attacker can cause worker connection handling to block by opening a connection to the authentication listener and delaying or withholding the client...

CVE-2026-7776

Boundary Community Edition and Boundary Enterprise “Boundary” workers are vulnerable to a denial-of-service condition during node enrollment TLS handshakes. An attacker with network access to the worker authentication listener may open a connection and delay or withhold the client certificate...

Incorrect Authorization

Overview pyload-ng is a The free and open-source Download Manager written in pure Python Affected versions of this package are vulnerable to Incorrect Authorization in the setconfigvalue process. An attacker can disable outbound TLS peer verification by setting the sslverify configuration to 'off...

Improper Enforcement of Behavioral Workflow

Overview Affected versions of this package are vulnerable to Improper Enforcement of Behavioral Workflow via the starttls function. An attacker can intercept and manipulate the communication by injecting a crafted response before the client completes sending the command, causing the connection to...

GHSA-VCGP-9326-PQCP net-imap vulnerable to STARTTLS stripping via invalid response timing

Summary A man-in-the-middle attacker can cause Net::IMAPstarttls to return "successfully", without starting TLS. Details When using Net::IMAPstarttls to upgrade a plaintext connection to use TLS, a man-in-the-middle attacker can inject a tagged OK response with an easily predictable tag. By sendi...

CVE-2026-7776 Boundary Workers Vulnerable to Denial of Service During TLS Handshake

Boundary Community Edition and Boundary Enterprise “Boundary” workers are vulnerable to a denial-of-service condition during node enrollment TLS handshakes. An attacker with network access to the worker authentication listener may open a connection and delay or withhold the client certificate...

Incus has an OVN TLS Verification that Accepts Peer-Supplied Roots

Summary Broken TLS validation logic in the OVN database connection logic could allow connections to an attacker's OVN database. OVN uses mTLS for authentication, so the attacker cannot actually perform a full man in the middle attack as they won't be able to authenticated with the real OVN...

Improper Authentication

Overview Affected versions of this package are vulnerable to Improper Authentication in the OVN database connection process. An attacker can gain unauthorized access to sensitive network configuration data by presenting a rogue self-signed certificate chain during the TLS handshake, which is...

CVE-2026-0073

In adbdtlsverifycert of auth.cpp, there is a possible bypass of wireless ADB mutual authentication due to a logic error in the code. This could lead to remote proximal/adjacent code execution as the shell user with no additional execution privileges needed. User interaction is not needed for...

pyOpenSSL: DTLS cookie callback buffer overflow

A flaw was found in pyOpenSSL. The setcookiegeneratecallback callback function can be used to generate DTLS cookies. When the callback returns a cookie string or byte sequence longer than 256 bytes, a buffer overflow can be triggered due to a missing bounds checking before copying the data to a...

aap-gateway: missing requestHeadersToRemove allows mTLS bypass via Subject header spoofing

A flaw was found in the AAP Gateway Envoy proxy configuration. The non-mTLS route to EDA event streams does not remove the Subject HTTP header from client requests, despite the source code defining requestHeadersToRemove for this header. An unauthenticated remote attacker can inject a spoofed...

JLSEC-2026-417 libcurl did not check the server certificate of TLS connections done to a host specified as an IP...

libcurl did not check the server certificate of TLS connections done to a host specified as an IP address, when built to use mbedTLS. libcurl would wrongly avoid using the set hostname function when the specified hostname was given as an IP address, therefore completely skipping the certificate...

JLSEC-2026-429 When doing TLS related transfers with reused easy or multi handles and altering the...

When doing TLS related transfers with reused easy or multi handles and altering the CURLSSLOPTNOPARTIALCHAIN option, libcurl could accidentally reuse a CA store cached in memory for which the partial chain option was reversed. Contrary to the user's wishes and expectations. This could make libcur...

Security Bulletin: pyOpenSSL TLS SNI Callback Exception Handling Flaw Allows Security Bypass

Summary pyOpenSSL is a Python wrapper around the OpenSSL library. Starting in version 0.14.0 and prior to version 26.0.0, if a user provided callback to settlsextservernamecallback raised an unhandled exception, this would result in a connection being accepted. If a user was relying on this...

USN-8227-1: curl vulnerabilities

It was discovered that curl incorrectly reused non-TLS connections when TLS was required in some STARTTLS configurations. A remote attacker could possibly use this issue to obtain sensitive information. CVE-2026-4873 It was discovered that curl incorrectly reused certain HTTP Negotiate connection...

ALPINE-CVE-2026-33846
