CVSS: 10.0EPSS: 0%CPEs: 4EXPL: 0CVE-2025-15366 – IMAP command injection in user-controlled commands
https://notcve.org/view.php?id=CVE-2025-15366
20 Jan 2026 — The imaplib module, when passed a user-controlled command, can have additional commands injected using newlines. Mitigation rejects commands containing control characters. Denis Ledoux discovered that Python incorrectly parsed email message headers. An attacker could possibly use this issue to inject arbitrary headers into email messages. This issue only affected python3.6, python3.7, python3.8, python3.9, python3.10, python3.11, python3.12, python3.13, and python3.14 packages. • https://github.com/python/cpython/commit/6262704b134db2a4ba12e85ecfbd968534f28b45 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
CVSS: 10.0EPSS: 0%CPEs: 5EXPL: 1CVE-2025-56005 – PLY 3.11 Arbitrary Code Execution
https://notcve.org/view.php?id=CVE-2025-56005
20 Jan 2026 — An undocumented and unsafe feature in the PLY (Python Lex-Yacc) library 3.11 allows Remote Code Execution (RCE) via the `picklefile` parameter in the `yacc()` function. This parameter accepts a `.pkl` file that is deserialized with `pickle.load()` without validation. Because `pickle` allows execution of embedded code via `__reduce__()`, an attacker can achieve code execution by passing a malicious pickle file. The parameter is not mentioned in official documentation or the GitHub repository, yet it is activ... • https://packetstorm.news/files/id/214433 • CWE-502: Deserialization of Untrusted Data •

https://notcve.org/view.php?id=CVE-2026-0989
15 Jan 2026 — A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested <include> directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk. It was discovered that libxml2 incorrectly handled maliciously crafted SGML catalog files. • https://access.redhat.com/security/cve/CVE-2026-0989 • CWE-674: Uncontrolled Recursion •

https://notcve.org/view.php?id=CVE-2026-0990
15 Jan 2026 — A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications.

https://notcve.org/view.php?id=CVE-2026-0976
15 Jan 2026 — A flaw was found in Keycloak. This improper input validation vulnerability occurs because Keycloak accepts RFC-compliant matrix parameters in URL path segments, while common reverse proxy configurations may ignore or mishandle them. A remote attacker can craft requests to mask path segments, potentially bypassing proxy-level path filtering. This could expose administrative or sensitive endpoints that operators believe are not externally reachable. • https://access.redhat.com/security/cve/CVE-2026-0976 • CWE-20: Improper Input Validation •

13 Jan 2026 — A flaw was found in libsoup’s WebSocket frame processing when handling incoming messages. If a non-default configuration is used where the maximum incoming payload size is unset, the library may read memory outside the intended bounds. This can cause unintended memory exposure or a crash. Applications using libsoup’s WebSocket support with this configuration may be impacted. This update for libsoup fixes the following issues. • https://access.redhat.com/security/cve/CVE-2026-0716 • CWE-805: Buffer Access with Incorrect Length Value •
