CVE-2026-52814
Description détaillée
Gogs is an open source self-hosted Git service. Prior to 0.14.3, the Gogs built-in Go SSH server is vulnerable to an unauthenticated, asymmetric Denial of Service (DoS) attack. The application accepts inbound TCP connections and passes them to golang.org/x/crypto/ssh.NewServerConn inside a new goroutine without enforcing any read/write deadlines on the underlying net.Conn. An unauthenticated attacker can open multiple TCP connections to the SSH port and simply withhold the SSH protocol banner. This forces the server to spawn an unbounded number of goroutines that block indefinitely waiting for socket I/O. This leads to complete File Descriptor (FD) exhaustion, preventing legitimate users from accessing the Git SSH service, and ultimately destabilizing the entire Gogs process (e.g., causing internal log rotation failures). This vulnerability is fixed in 0.14.3.

CVE-2026-39955
Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have pre-authentication SQL Injection via unanchored FILTER_VALIDATE_REGEXP in graph_view.php. This issue has been fixed in version 1.2.31.
CVE-2026-39948
Cacti is an open source performance and fault management framework. In versions 1.2.30 and prior, the rfilter request parameter is retrieved via the raw accessor grv() (rather than gfrv() with FILTER_VALIDATE_IS_REGEX validation) and concatenated directly into RLIKE SQL clauses in lib/html_graph.php and lib/html_tree.php, which are reachable pre-authentication through graph_view.php on installations with guest graph viewing enabled. Because the unbalanced-quote payload bypasses the regex validation that would otherwise reject it, an unauthenticated attacker can inject arbitrary SQL to compromise the confidentiality, integrity, and availability of the database. This advisory is similar to GHSA-69gg-mjfm-jjpc. This issue has been fixed in version 1.2.31.
