undici: undici: Man-in-the-Middle attack via ignored TLS options with SOCKS5 proxy

A flaw was found in undici. When undici's ProxyAgent is configured with a SOCKS5 proxy Uniform Resource Identifier URI, it silently ignores Transport Layer Security TLS options, such as custom Certificate Authorities CAs. This allows a remote attacker to perform a Man-in-the-Middle MITM attack,...

CVE-2026-9547

The CVE-2026-9547 issue affects libcurl when performing SCP/SFTP transfers with CURLOT_SSH_KEYFUNCTION in the SSH key callback. A host-key type mismatch for a known_hosts entry may be silently accepted, bypassing the intended validation and allowing connections to succeed without warning, which e...

net-imap: ruby: Net::IMAP: Information disclosure via man-in-the-middle attack bypassing TLS

A flaw was found in the Ruby net-imap library. When upgrading a cleartext IMAP connection to TLS using the Net::IMAPstarttls method, the library improperly handles certain responses received during STARTTLS negotiation. A man-in-the-middle MITM attacker can inject a predicted tagged OK response...

gnutls: gnutls: Certificate validation bypass due to oversized Subject Alternative Name

A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name SAN could cause the validation process to incorrectly fall back to checking the Common Name CN field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to...

gnutls: gnutls: Security bypass due to incorrect name constraint handling

A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities CAs only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate...

CVE-2025-15661

A flaw in libssh2's sftpsymlink function allows a malicious SSH server or man-in-the-middle attacker to trigger an out-of-bounds heap read via a crafted SSHFXPNAME response. This can disclose heap memory contents or crash the application, causing a denial of service DoS. Mitigation Implement stri...

CVE-2026-44017

A flaw was found in Docling. The EasyOCR model download functionality improperly extracts ZIP archives without validating member paths, enabling Zip Slip attacks. If an attacker compromises the model download source e.g., via a supply chain or Man-in-the-Middle MITM attack, they could write...

SUSE CVE-2026-42246

Net::IMAP implements Internet Message Access Protocol IMAP client functionality in Ruby. Prior to versions 0.3.10, 0.4.24, 0.5.14, and 0.6.4, a man-in-the-middle attacker can cause Net::IMAPstarttls to return "successfully", without starting TLS. This issue has been patched in versions 0.3.10,...

CURL-CVE-2026-9547 SSH improper host validation

When a libcurl-based application performs transfers via SCP:// or SFTP:// and utilizes the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This vulnerability occurs when a server presents a host key type that does not match the specific key type already recorded for th...
