BIT-PILLOW-2026-59204 Pillow JPEG2000 tiled decode retains a growing scratch buffer and can be used for denial of service

Pillow is a Python imaging library. From 8.2.0 through 12.2.0, src/libImaging/Jpeg2KDecode.c accumulates totalcomponentwidth across every tile in a JPEG2000 image instead of recomputing it per tile, allowing a crafted tiled JPEG2000 file to force substantially higher transient memory usage and...

PT-2026-60378

Name of the Vulnerable Software and Affected Versions websocket-driver versions prior to 0.8.1 Description Draft versions of the WebSocket protocol in the handler include a length header that allows an arbitrarily large integer to be encoded as bytes with the high bit set. A server or client can...

DEBIAN-CVE-2026-47736

Puma is a Ruby/Rack web server built for parallelism. From 5.5.0 until 7.2.1 and 8.0.2, when PROXY protocol v1 support is enabled, Puma reads incoming bytes into an internal buffer while waiting for CRLF to determine whether a PROXY v1 line is present, allowing an attacker that continuously sends...

CVE-2026-47736

Summary: CVE-2026-47736 affects the Puma Ruby/Rack web server when PROXY protocol v1 is enabled. In affected releases (5.5.0 up to 7.2.1 and 8.0.2), Puma reads incoming bytes into an internal buffer while waiting for CRLF to detect a PROXY v1 line, allowing an attacker to send data without CRLF a...

CVE-2026-15709 Soupwebsocketextensiondeflate: libsoup: libsoup: websocket permessage-deflate unbounded decompression remote denial of service

A flaw was found in libsoup's WebSocket implementation when using the permessage-deflate extension. The extension's decompression loop inflate processes data in chunks without enforcing an upper boundary limit on the output buffer size. While libsoup limits the incoming compressed frame size via...

CVE-2026-49835

A flaw was found in Sigstore Timestamp Authority. An unauthenticated remote attacker can exploit this vulnerability by sending requests with arbitrary HTTP paths and methods. This leads to the creation of an excessive number of unique metric labels, causing unbounded memory growth and a denial of...

PYSEC-2026-2992 pyLoad: Unbounded Memory Growth Leading to DoS and Potential DDoS in EventManager

Description: The EventManager module in pyload manages a list of Client instances for subscribing to events. The addition of each unique uuid from the getevents API causes the creation of a Client instance that gets appended to the clients list. Although there is a clean method available in the...

PYSEC-2026-2533 LTI JupyterHub Authenticator: Unbounded Memory Growth via Nonce Storage (Denial of Service)

Summary The LTI 1.1 validator stores OAuth nonces in a class-level dictionary that grows without bounds. Nonces are added before signature validation, so an attacker with knowledge of a valid consumer key can send repeated requests with unique nonces to gradually exhaust server memory, causing a...

undici: undici: Denial of Service due to unbounded memory growth via WebSocket frames

A flaw was found in undici. A malicious WebSocket server can exploit this by streaming numerous small or empty continuation frames. This can bypass per-frame and cumulative-size validation, leading to unbounded memory growth in the client process. The primary consequence is memory exhaustion,...
