CVE-2026-7263 is a medium-severity PHP denial-of-service issue in DOMNode::C14N(). In affected PHP releases, incorrect XML processing can corrupt the document structure into a circular linked list, and later processing may loop indefinitely. The practical risk is application hang or service degradation for workloads that canonicalize or further process XML documents.
CVE-2026-6104 is a PHP mbstring vulnerability disclosed on 2026-05-10. In affected PHP 8.4.* and 8.5.* releases, an encoding name containing an embedded NUL byte can make mbstring incorrectly treat a strncasecmp() match as proof that the strings are the same length. That logic error can lead to an out-of-bounds read of global memory, which may result in a crash or information disclosure.
CVE-2026-42245 is a denial-of-service issue in Ruby’s Net::IMAP client library. Before versions 0.4.24, 0.5.14, and 0.6.4, Net::IMAP::ResponseReader can take quadratic time when processing large responses with many string literals. An attacker controlling or emulating an IMAP server can use crafted responses to exhaust client CPU and disrupt service. The issue was publicly recorded on 2026-05-09 and is fi [truncated]
CVE-2026-41893 affects Signal K Server versions before 2.25.0. The HTTP login endpoints are rate-limited, but the WebSocket login path accepts username/password messages without the same protection, allowing repeated guessing at the pace of bcrypt verification. The issue was addressed in version 2.25.0.
CVE-2026-42309 is a medium-severity heap buffer overflow in Pillow's coordinate handling. Nested lists passed to APIs that accept coordinates could be recursively unpacked beyond the allocated buffer. The issue affects Pillow from 11.2.1 up to, but not including, 12.2.0, and is fixed by validating coordinate lists to contain exactly two numeric values.
CVE-2026-42308 is a Medium-severity issue in Pillow, the Python imaging library, where excessively large glyph advance values can cause an integer overflow while Pillow tracks the current position. The issue is patched in Pillow 12.2.0. The available source record ties the weakness to CWE-190 and points to the 12.2.0 release and associated GitHub security advisory.
CVE-2025-65134 is a reflected cross-site scripting (XSS) issue affecting manikandan580 School-management-system 1.0 in /studentms/admin/contact-us.php via the email POST parameter. NVD records the issue as CVSS 3.1 6.1 (medium), maps it to CWE-79, and marks the record Deferred. Because exploitation requires user interaction, the main concern is browser-side script execution in a victim’s session when untr [truncated]
CVE-2026-22920 is listed in the supplied official records as rejected/withdrawn, which means there is no validated vulnerability description to assess from this record alone. The available data does not identify a vendor, product, CVSS score, CPE, or weakness information. For defenders, the main takeaway is administrative: keep your vulnerability-management and ticketing data aligned with the official sta [truncated]
