CVE-2026-58263 Jodit Editor: Mutation XSS in jodit clean-html via a MathML/style rawtext carrier

Jodit Editor is a WYSIWYG editor with a built-in file browser & image editor. In versions prior to 4.12.28, the built-in clean-html sanitizer can be bypassed by a MathML/ carrier that hides a dangerous element from the sanitizer's element walk, so a no-interaction event handler survives into the...

CVE-2026-58263

CVE-2026-58263 affects Jodit Editor prior to 4.12.28. The built‑in clean-html sanitizer can be bypassed via a MathML/ carrier, allowing a no‑interaction event handler (e.g., onload) to survive in the editor value. When attacker‑supplied HTML is rendered (element.innerHTML = editor.value), the han...

CVE-2026-54898 (Oj gem) affects the Ruby JSON parser Oj in versions before 3.17.2. The vulnerability occurs when a SAJ/SAJ2 callback mutates the input string during parsing, causing the C engine’s raw pointer into Ruby’s string buffer to become dangling and resulting in a heap use-after-free on t...

GHSA-JFC7-64V2-MR8C @sigstore/core has DSSE payloadType type-binding failure

Impact The preAuthEncoding function in @sigstore/core uses Node.js 'ascii' encoding when converting the PAE Pre-Authentication Encoding string to bytes. This allows payloadType to be mutated after signing without invalidating the signature, breaking the type-binding guarantee that DSSE is designe...

Inherited Circuits, Learned Semantics: How Fine-Tuning Creates Evasion Vulnerabilities Invisible to Standard Evaluation

LLMs fine-tuned for security classification are usually evaluated on held-out examples from the same distribution as their training data. We show that this can miss vulnerabilities introduced by fine-tuning itself: models can learn token-level indicator semantics that preserve canonical accuracy...

CVE-2026-49983

Summary of CVE-2026-49983 details (Deno): Deno’s process.loadEnvFile() incorrectly bypasses env permission checks. It only verifies read permission on the dotenv file and then writes all keys from the file into process.env, even if env access is denied. This means that with --allow-read and a wri...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in the parse function. An attacker can cause memory corruption by mutating the input JSON string during parsing callbacks, which leads to the parser accessing freed memory. Remediation Upgrade oj to version 3.17.3 or...

CVE-2026-49291

mcp-memory-service is a semantic memory layer for AI applications. Prior to version 10.65.3, the HTTP MCP JSON-RPC endpoint at /mcp requires only OAuth read scope for all requests, then dispatches tools/call directly to handlers that include mutating tools. A read-only OAuth client can call...

CVE-2026-49291

mcp-memory-service (semantic memory layer for AI apps) exposed the HTTP MCP JSON-RPC endpoint at /mcp such that OAuth read scope allowed mutating actions. Before patch 10.65.3, a read-only OAuth client could invoke tools/call to reach store_memory and delete_memory, bypassing REST write scope che...
