———A vulnerability was found in Travisun Opptrix 0.4.0. Affected is the function Buffer.concat of the file /api/channels/webhook/ of the component preParsing handler. Performing a manipulation results in denial of service. The attack can be initiated remotely. The exploit has been made public and could be used. The project has been completely taken offline and deprecated. The project maintainer explains: "The mentioned security risk was a design flaw that manifested primarily in local environments during earlier stages of version development. We previously addressed and resolved this specific risk; however, because the project was restricted to a small learning scope and the main versions were intended to run exclusively on localhost, the security fix was only pushed directly to our GitHub repository before it went private." This vulnerability only affects products that are no longer supported by the maintainer.4h CVE-2026-1138727.5 HIG

——11multer is a middleware for Node.js that handles multipart/form-data file uploads. In versions from 2.0.0 before 2.5.0, when multer is configured with an asynchronous fileFilter, a single request can crash the Node.js process. If the request is aborted while one file's asynchronous fileFilter is still pending, the pending callback later resumes a parsing stream that multer has already torn down, and the underlying parser emits an error on a stream that no longer has an error listener, which Node raises as an unhandled error event so the process exits. Any application using multer with an asynchronous fileFilter is affected regardless of storage engine, while uploads using a synchronous fileFilter are not affected. The issue is fixed in multer 2.5.0, and users should upgrade to 2.5.0 or later. As a workaround, use a synchronous fileFilter.2d CVE-2026-1014023.7 LOW

——6A weakness has been identified in MemTensor memmy-agent up to 1.0.9/1.1.1/1.2.2. The impacted element is the function requireAdminWrite of the file Memory/src/server/http.ts of the component Memory Service. This manipulation causes resource consumption. Remote exploitation of the attack is possible. The attack is considered to have high complexity. The exploitability is regarded as difficult. The exploit has been made available to the public and could be used for attacks. The exploit is partially overstated. While "POST /api/v1/admin/shutdown" accepts unauthenticated requests when no token is configured, it’s designed for local use and later received cross-origin fixes. Unauthenticated endpoint exposure is confirmed; browser-triggered DoS remains likely but depends on specific browser behavior.3d
