PraisonAI MCP HTTP server has unauthenticated unbounded session accumulation (memory exhaustion; session TTL never enforced)

Summary The PraisonAI MCP HTTP-stream server creates a new in-memory session on every initialize request and never removes it. The cleanup routine that would expire sessions cleanupsessions is defined but never called anywhere in the codebase, and the configured session TTL is never enforced. The...

CVE-2026-55531 PraisonAI: Unauthenticated unbounded session accumulation in the PraisonAI MCP HTTP server (memory exhaustion; session TTL never enforced)

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.58, the MCP HTTP Stream mcppost handler creates a new sessions entry for every initialize request but does not call cleanupsessions or enforce a maximum. An unauthenticated caller can exhaust memory. The fix invokes cleanup and limit...

CVE-2026-55531

PraisonAI 's MCP HTTP Stream server (prior to 4.6.58 ) suffers from unbounded in-memory session accumulation. Each unauthenticated initialize request creates a new entry in the _sessions dictionary, but the existing _cleanup_sessions method is never invoked and no maximum session cap is enforced,...

CVE-2026-46405

A flaw was found in OpenBao, an identity-based secrets management system. When the Kerberos authentication method processes a GET request or an Authorization: Negotiate header, it inadvertently creates authentication tokens that are not accessible to the caller and are hidden by an error message...

io.quarkus/quarkus-rest: io.quarkus/quarkus-vertx-http: io.quarkus.resteasy.reactive/resteasy-reactive: Quarkus REST - Unbounded multipart MIME part-header accumulation allows remote OOM denial of service

A flaw was found in Quarkus REST. An unauthenticated remote attacker can exploit this vulnerability by sending a crafted multipart/form-data request with an excessively large header section. This unbounded accumulation of MIME part-header bytes can exhaust the Java Virtual Machine JVM heap memory...

Allocation of resources without limits vulnerability in elixir-mint mint allows a remote HTTP/2 server to exhaust memory on the client host and cause a denial of service. The Mint.HTTP2.handlecontinuation/3 function in lib/mint/http2.ex accumulates the header-block fragment carried by each HTTP/2...

CVE-2026-58229 Unbounded HTTP/1 response-header and chunked-trailer accumulation in Mint causes memory-exhaustion DoS

Allocation of resources without limits vulnerability in elixir-mint mint allows a remote HTTP server to exhaust memory on the client host and cause a denial of service. The Mint.HTTP1.decodeheaders/5 and Mint.HTTP1.decodetrailerheaders/4 functions in lib/mint/http1.ex accumulate every parsed...

CVE-2026-58229

The CVE-2026-58229 issue affects the Elixir Mint HTTP client. Mint.HTTP1.decode_headers/5 and Mint.HTTP1.decode_trailer_headers/4 accumulate all parsed response headers and trailer fields into a request.headers_buffer without a cap, and decoding uses unlimited per-line/packet limits. A malicious ...

py7zr: O(n^2) algorithmic complexity DoS in PackInfo._read()

SummaryPackInfo.read uses an On^2 cumulative sum pattern where numstreams is read directly from the archive header. A crafted .7z archive with a large numstreams value causes excessive CPU consumption during SevenZipFile.init — no extraction is needed. A 50 KB archive takes 7 seconds of CPU time...

GNU Wget through 1.25.0, fixed in commit dd692d9, contains a heap buffer overflow vulnerability in the htmlquotestring function in src/convert.c that allows a remote attacker to trigger memory corruption by supplying a crafted HTML attribute with a large number of characters requiring entity...

python-socketio: Binary attachment accumulation can cause denial of service

Impact The python-socketio server stores binary EVENT and ACK messages in memory while it waits to receive their binary attachments. Once all the attachments are received, these messages are then processed. An attacker can submit a binary message and intentionally omit sending one or more of its...
