An infinite loop in PgBouncer 1.20.0 through 1.26.0 allows an unauthenticated remote attacker to cause a denial of service. A StartupMessage whose options parameter contains an empty parameter name, such as "-c=", makes the ignore_startup_parameters list lookup loop forever. Because PgBouncer serves all clients from a single process, this saturates a CPU core and makes PgBouncer unresponsive to all clients until the process is restarted.

CVE-2026-172797.7 ALT—
———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to cause a denial of service due to uncontrolled resource consumption. Certain requests can cause internal processing to stall, which could make the service unavailable.4hCVE-2026-591715.9 MÉD—
———JSON-java is a reference implementation of a JSON package in Java. From version 20150729 through 20260522, JSONTokener.nextSimpleValue can accumulate unbounded numeric tokens before JSONObject.stringToNumber passes them to BigInteger or BigDecimal conversion without a length limit. An application that parses attacker-controlled JSON or XML through JSONObject, JSONArray, or XML.toJSONObject can spend super-linear CPU time converting a sufficiently long numeric literal, blocking request-handling threads and causing denial of service. Strict mode and keep-strings settings in JSONParserConfiguration do not prevent the affected conversion path. Version 20260719 limits numeric conversion length.12hCVE-2026-1233567.5 ALT—
——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 0.9.1.14hCVE-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.15hCVE-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 3.15.2.15hCVE-2026-1237855.5 MÉD—
——0Fluxbox through 1.3.7 contains an infinite loop vulnerability in Menu::updateMenu() in src/FbTk/Menu.cc that allows attackers to hang the window manager via crafted style geometry values. Attackers can supply a style with an oversized unbounded menu.titleHeight so the column loop never terminates, causing sustained CPU use and denial of service at startup.16h
