EUVD-2026-41875

A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pnmscannergettoken function writes a null terminator one byte past the end of a stack-allocated buffer due to an off-by-one error in the loop boundary check. This could lead to memory corruption,...

CVE-2026-50021

A flaw was found in pnpm, a package manager. An attacker who can modify the pnpm-lock.yaml file and control the package registry can exploit this vulnerability. By removing the integrity field from the lockfile and serving altered package content, the pnpm install --frozen-lockfile command can...

postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...

CVE-2026-12252

A flaw was found in the nltk library. Several Stanford interface classes within nltk are susceptible to arbitrary code execution. This vulnerability allows a local attacker to execute malicious code by providing an untrusted Java Archive JAR file, as the system lacks integrity verification for...

kernel: mptcp: fix slab-use-after-free in __inet_lookup_established

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...

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,...

erb: ERB: Arbitrary code execution via deserialization bypass

A flaw was found in ERB, a templating system for Ruby. An attacker who can trigger deserialization of untrusted data in a Ruby application can bypass existing protections. This vulnerability allows for arbitrary code execution by exploiting specific public methods that evaluate template source...

python: cpython: Python: Arbitrary code execution via command injection in webbrowser.open() API

A flaw was found in the Python webbrowser.open API. If a specially crafted URL containing "%action" is processed, an attacker could bypass a previous mitigation for CVE-2026-4519. This bypass allows for command injection into the underlying shell, potentially leading to arbitrary code execution...

golang.org/x/net/html: golang.org/x/net/html: Arbitrary code execution via Cross-Site Scripting

A flaw was found in golang.org/x/net/html. A remote attacker could exploit this vulnerability by providing specially crafted HTML. When this arbitrary HTML is parsed and rendered, it can result in an unexpected HTML tree, bypassing input sanitization. This can be leveraged to execute Cross-Site...
