——15MessagePack for C# is a MessagePack serializer for C#. Prior to 2.5.303 and 3.1.9, deserializing attacker-controlled MessagePack data as System.Object through PrimitiveObjectFormatter can cause excessive memory allocation. The formatter allocates an object[] from each declared array length before the configured object-graph depth limit rejects the input, while nested array headers can reuse the same trailing unread bytes to satisfy per-header length validation. A comparatively small payload can therefore keep many large arrays alive at once. When an attacker can submit such data repeatedly, the allocations can cause severe managed-heap pressure, excessive garbage collection, process termination, or loss of service. Exposure requires an application to deserialize untrusted data through the affected formatter path and permit repeated attacker-controlled submissions, such as a reachable ASP.NET Core SignalR hub method with an object parameter and AddMessagePackProtocol() enabled. This issue is fixed in versions 2.5.303 and 3.1.9.4dCVE-2026-71436—46.7%
——14Mermaid is a JavaScript tool that uses Markdown-inspired text to create and modify diagrams and charts. From version 10.6.0 until 10.9.8 and 11.16.1, Mermaid XY Charts are vulnerable to an infinite loop denial of service in the setXAxisRangeData function when configuring an X-Axis with invalid parameters. Because each loop iteration appends an element to an array, this generally causes a RangeError to appear after a few seconds, but it may instead cause the page or JavaScript process to crash from memory exhaustion, depending on the environment. This issue is fixed in versions 10.9.8 and 11.16.1.42dCVE-2026-187726.5 MED27.7%

——13veraPDF PDF parser is a PDF parser for veraPDF. Prior to 1.30.2 and 1.31.23, veraPDF-parser contains a denial-of-service vulnerability in veraPDF-parser/src/main/java/org/verapdf/pd/font/type1/Type1FontProgram.java and veraPDF-parser/src/main/java/org/verapdf/parser/postscript/PSOperator.java, where a crafted Type 1 font /FontDescriptor /FontFile program can execute unbounded PostScript array allocation, a zero-increment for loop, or self-recursive toExecute user dictionary lookups and exhaust validator memory, CPU, or stack. This issue is fixed in versions 1.30.2 and 1.31.23.82dCVE-2026-54080—43.2%
