CVE-2026-57940: HTMLy 3.1.1 contains a Server-Side Request Forgery (SSRF) vulnerability in the RSS feed import functionality. The function get_feed() in system/admin/admin.php passes user-supplied $feed_url directly to file_get_contents() without any validation. An authenticated attacker with administrative privileges can exploit this by entering a crafted URL (e.g., http://dnslog.example.com/ , file:///etc/pa...

CVE-2026-53914: In JetBrains Kotlin before 2.4.20 code execution was possible via unsafe deserialization in the build cache metadata

CVE-2026-57926: In JetBrains YouTrack before 2026.2.16593 the websandbox bridge was vulnerable to a prototype pollution attack

CVE-2026-57925: In JetBrains YouTrack before 2026.2.16593 improper access control allowed reading saved queries and tags

CVE-2026-57924: In JetBrains YouTrack before 2026.2.16593 default role configuration exposed excessive user profile details

CVE-2026-7531: Use-after-free in PQC hybrid key-share handling: Use-after-free in PQC hybrid key-share handling. This is an incomplete-fix follow-up to CVE-2026-5460 (released in 5.9.1): a malicious TLS 1.3 server sending a truncated PQC hybrid KeyShare can still trigger the error cleanup path to operate on freed memory.

CVE-2026-6731: X.509 name constraint bypass via Subject CN treated as a DNS name: X.509 name constraint bypass via the Subject Common Name when treated as a DNS-type name. A certificate whose Subject CN violates an issuing CA's DNS name constraints could be accepted.

CVE-2026-6681: PKCS#7 decode ignores caller output buffer size, writing past buffer bounds: The PKCS#7 decode path ignores the caller-supplied output buffer size (outputSz), allowing decoded content to be written past the bounds of the provided buffer. This affects wolfSSL 5.9.0 and earlier and was fixed in the 5.9.1 release.

CVE-2026-6679: DTLS 1.3 ACK serialization heap buffer overflow via integer truncation: A heap buffer overflow could occur in the DTLS 1.3 ACK serialization path before the connecting peer is authenticated. The buffer overflow was due to an integer truncation when computing the length of the ACK record-number list, causing an undersized buffer to be allocated and then overrun. This affects builds using DTLS 1....

CISA Known Exploited Vulnerabilities

CVE-2026-20230 Cisco Unified Communications Manager: Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) contain a server-side request forgery (SSRF) Vulnerability that could allow an unauthenticated, remote attacker to write files to the underlying operating system that could be used later to elevate to root.

CVE-2026-12569 PTC Windchill and FlexPLM: PTC Windchill and FlexPLM contains an improper input validation vulnerability allowing an unauthenticated, remote attacker to execute arbitrary code by sending a malicious request to the network.

CVE-2026-34910 Ubiquiti UniFi OS: Ubiquiti UniFi OS contains an improper input validation vulnerability which could allow a malicious actor with access to the network to conduct command injection.

CVE-2026-34909 Ubiquiti UniFi OS: Ubiquiti UniFi OS contains a path traversal vulnerability which could allow a malicious actor with access to the network to access files on the underlying system that could be manipulated to access an underlying account.

CVE-2025-67038 Lantronix EDS5000: Lantronix EDS5000 contains a code injection vulnerability that could allow attackers to inject arbitrary OS commands into the username parameter. Injected commands are executed with root privileges.

Additional information

EUVD (European Union Vulnerability Database) is maintained by ENISA (European Union Agency for Cybersecurity), under the European Union’s regulatory umbrella, serving as a centralized platform for vulnerability reporting specifically aligned with the EU’s legal frameworks such as NIS2 and the Cyber Resilience Act (CRA)

EUVD complements the CVE system by aggregating CVE data, but also assigns its own EUVD IDs to vulnerabilities, offers enriched metadata tailored for EU policies and compliance, and may highlight vulnerabilities particularly relevant to the European market.

Most vulnerabilities catalogued in EUVD will have both a CVE-ID and an EUVD-ID, acting as cross-references.
