Security Bulletin: Log4j Core TLS hostname verification bypass via verifyHostName XML attribute allows man-in-the-middle attacks on SMTP/Socket/Syslog appenders.

Summary Vulnerabilities have been identified in Apache Log4j Core versions up to 2.25.3 affecting TLS security, log integrity, and XML output handling. The first exposes SMTP, Socket, and Syslog appenders to man-in-the-middle attacks due to silently ineffective hostname verification; the second...

RUSTSEC-2026-0194 Quadratic run time when checking a start tag for duplicate attribute names

BytesStart::attributes returns an Attributes iterator which, by default withcheckstrue, rejects a start tag that repeats an attribute name. For each attribute yielded, the iterator compared the new name against every name seen so far in the same tag using a linear scan, so a start tag with N...

PYSEC-2026-385 Remote code execution in pytorch lightning

A remote code execution RCE vulnerability exists in the lightning-ai/pytorch-lightning library version 2.2.1 due to improper handling of deserialized user input and mismanagement of dunder attributes by the deepdiff library. The library uses deepdiff.Delta objects to modify application state base...

CVE-2026-57435

A flaw was found in Nokogiri, an XML and HTML library for Ruby. This use-after-free vulnerability occurs when replacing the value of an XML attribute. If a Ruby wrapper already points to the attribute's child node, the underlying native child node can be freed while the wrapper remains accessible...

CVE-2026-58050

libssh2 through 1.11.1 reads an attacker-controlled 32-bit attribute count from a publickey-subsystem response and uses it in the allocation numattrs sizeoflibssh2publickeyattribute without bounds checking, so on 32-bit platforms the multiplication overflows to an undersized buffer. A malicious S...

CVE-2026-58050

CVE-2026-58050 affects libssh2 up to 1.11.1. The publickey subsystem reads an attacker-controlled 32-bit attribute count and uses it in the allocation num_attrs * sizeof(libssh2_publickey_attribute) without bounds checking. On 32-bit platforms, this multiplication can overflow, producing an under...
