Descrição técnica

Open WebUI 0.11.0 before 0.11.4 contains a denial of service vulnerability in the automation recurrence-rule validator, whose sub-daily frequency guard parses rule text more strictly than the calendar library that executes it. Users permitted to create automations can submit whitespace-folded rules (or, in 0.11.0, lowercase frequencies or omitted RRULE prefixes) that expand per-second synchronously, blocking the shared event loop for minutes per request and on every scheduler poll.

——0GROBID is machine learning software for extracting information from scholarly documents. Prior to 0.9.1, the unauthenticated /api/modelTraining endpoint calls GrobidRestProcessTraining.trainModel in GrobidRestProcessTraining.java, where each request creates Executors.newFixedThreadPool(1), submits a training task, and leaves the executor running. Repeated requests permanently retain JVM worker threads and can exhaust process or operating-system thread capacity, degrading or stopping request processing. This issue is fixed in version 0.9.1.8h CVE-2026-1237484.3 MÉD

——0A security flaw has been discovered in chenyme grok2api up to 3.1.6. Affected by this vulnerability is the function proxyVoiceWebSocket of the file backend/internal/transport/http/inference/voice_ws_handler.go of the component WebSocket Proxy. The manipulation results in resource consumption. The attack may be launched remotely. Upgrading to version 3.1.7 addresses this issue. The patch is identified as 7ad0f791f0a9eb5a0ddfe38ac4dfcef01e19a6d4. It is suggested to upgrade the affected component.9h CVE-2026-1026507.5 ALT

——0Nuxt Content is the file-based CMS for Nuxt applications, powered by Markdown and Vue components. From 3.0.0 until 3.15.2, the unauthenticated POST /__nuxt_content/:collection/query endpoint accepts an attacker-controlled sql field in src/runtime/api/query.post.ts and permits expensive SQLite expressions. Version 3.0.0 performed no query validation; in affected releases using assertSafeQuery in src/runtime/internal/security.ts, the reported validation gap rejects a short list of SQL command keywords in WHERE clauses but permits function calls including randomblob(), zeroblob(), hex(), and length(). The query reaches the synchronous better-sqlite3 sink in src/runtime/internal/database.server.ts, allowing a single remote request to consume substantial CPU and memory while blocking the Node.js event loop and all concurrent request handling. Fully static prerendered deployments that do not expose the server endpoint are not affected. This issue is fixed in version 3.15.2.9h CVE-2026-772997.5 ALT

——8Regexp2 is a feature-rich RegExp engine for Go. Prior to version 2.3.0, when regexp2 compiles and matches a pattern containing a large fixed-count quantifier applied to a zero-width subexpression — e.g. (?:){50000000} — the match engine executes the empty loop body m-1 times, pushing two integers onto the backtracking stack on every iteration. Because the parser accepts any repetition count up to math.MaxInt32 and the backtracking stack grows without bound, a pattern of fewer than 20 bytes matched against an empty input can force multi-gigabyte allocation and OOM-kill the process. MatchTimeout does not fully mitigate this because the memory is allocated faster than the 100 ms timeout clock can fire. This issue has been patched in version 2.3.0.9h CVE-2026-829657.5 ALT

——13A flaw was found in the SAML implementation of Keycloak, an open-source identity and access management solution. The SAML Artifact Resolution and ECP SOAP endpoints do not properly limit the size or complexity of incoming XML requests. An unauthenticated remote attacker can exploit this by sending specially crafted, large XML messages that cause the server to consume excessive memory. This leads to the application running out of memory and crashing, resulting in a denial of service for all users.10h CVE-2026-494077.7 ALT

——7OpenHuman is an open-source agent harness available as a desktop application and Rust library. Before version 0.57.44, its local /ws/dictation WebSocket endpoint lacks client authentication and browser-origin validation. An unauthenticated client, including a malicious web page able to reach the endpoint, can submit audio and trigger resource-intensive speech-to-text processing. Earlier affected versions also accumulate audio in an unbounded buffer, allowing continuous streaming to exhaust process memory. These conditions can degrade performance, exhaust resources, or crash the application. This issue is fixed in version 0.57.44.1d
