Descripción técnica

Starman versions before 0.4019 for Perl allow a stalled request body to hold a worker indefinitely, as read_timeout covers only the headers. Content-Length and chunked request bodies are read with blocking reads and no deadline. A client that sends complete headers and then stalls or trickles the body keeps the worker waiting until it disconnects. A remote attacker can take every worker with a few such connections, five with the default worker count, so the server stops answering requests. Version 0.4019 applies read_timeout to each wait for body data and adds a body_timeout limit, 300 seconds by default, on the total time to read a body.

——0A vulnerability was determined in NocoDB up to 2026.07.0. This vulnerability affects the function UserRefreshToken.deleteAllUserToken of the file /auth/user/signup of the component PublicApiLimiterGuard. This manipulation causes allocation of resources. The attack is possible to be carried out remotely. The attack is considered to have high complexity. It is stated that the exploitability is difficult. Code-verified absence of in-app rate limiting on the unauthenticated signup and password-forgot endpoints and per-request refresh/OAuth token invalidation, but the vendor documents the pass-through limiter as intentional design. The vendor deleted the GitHub issue for this vulnerability without any explanation. Afterwards the vendor was contacted early about this disclosure via email but did not respond in any way.7h CVE-2026-115824—

——0Starman versions before 0.4019 for Perl allow memory exhaustion via unbounded buffering of chunked request bodies. The chunked body decoder keeps each chunk in memory until the whole chunk and its CRLF have arrived, and sets no limit on the length of a chunk-size line. A client that declares a huge chunk size and streams data, or sends a chunk-size line that never ends, grows the buffer for as long as it keeps sending. A remote attacker can exhaust worker memory with a single connection.20h CVE-2026-1161797.5 ALT

——0vLLM from 0.18.0 before 0.31.0 contains a resource exhaustion vulnerability that allows API clients to bypass the video/jpeg frame-count cap by overriding num_frames through media_io_kwargs. Attackers can set num_frames to -1 with a large inline video so VideoMediaIO.load_base64 decodes every frame, exhausting memory and crashing the API frontend.23h CVE-2026-1161433.3 BAJ

——0ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a policy bypass in the PS, PDF and XPS decoders that allows the security policy's list length limit on scene selection to be circumvented. Attackers supplying a specific argument can cause ImageMagick to process more scenes than permitted, potentially exhausting resources.23h CVE-2026-1157787.5 ALT

——14Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 26.10.0rc1, twisted.conch.telnet.Telnet.dataReceived appends every byte received after IAC SB to a persistent subnegotiation buffer until IAC SE is received, without applying a maximum length. Telnet option negotiation occurs before authentication, so an unauthenticated peer can omit the terminator and continuously grow the buffer. The resulting memory exhaustion can terminate the process and every service it hosts. This issue is fixed in version 26.10.0rc1.3d CVE-2026-1157767.5 ALT

——13Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 26.10.0rc1, twisted.words.protocols.irc.IRC.dataReceived retains all bytes received without a line feed in its per-connection buffer and applies no maximum line length. The twisted.words.service.IRCUser server subclass inherits this behavior, and buffering occurs before PASS, NICK, or USER authentication commands. An unauthenticated connection can continuously grow the buffer until the shared server process runs out of memory and drops all users. This issue is fixed in version 26.10.0rc1.3d
