PYSEC-2026-1107 AIOHTTP vulnerable to DoS when bypassing asserts
Summary When assert statements are bypassed, an infinite loop can occur, resulting in a DoS attack when processing a POST body. Impact If optimisations are enabled -O or PYTHONOPTIMIZE=1, and the application includes a handler that uses the Request.post method, then an attacker may be able to...
PYSEC-2026-1833 pypdf possibly loops infinitely when reading DCT inline images without EOF marker
Impact An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires parsing the content stream of a page which has an inline image using the DCTDecode filter. Patches This has been fixed in pypdf==6.1.3. Workarounds If you cannot upgrade yet, consider...
PYSEC-2026-1563 LlamaIndex Improper Handling of Exceptional Conditions vulnerability
A vulnerability in the LangChainLLM class of the run-llama/llamaindex repository, version v0.12.5, allows for a Denial of Service DoS attack. The streamcomplete method executes the llm using a thread and retrieves the result via the getresponsegen method of the StreamingGeneratorCallbackHandler...
PYSEC-2026-1290 DB-GPT Uncontrolled Resource Consumption vulnerability
A Denial of Service DoS vulnerability in the multipart request boundary processing mechanism of eosphoros-ai/db-gpt v0.6.0 allows unauthenticated attackers to cause excessive resource consumption. The server fails to handle excessive characters appended to the end of multipart boundaries, leading...
PYSEC-2026-1975 Tornado has an HTTP cookie parsing DoS vulnerability
The algorithm used for parsing HTTP cookies in Tornado versions prior to 6.4.2 sometimes has quadratic complexity, leading to excessive CPU consumption when parsing maliciously-crafted cookie headers. This parsing occurs in the event loop thread and may block the processing of other requests. See...
PYSEC-2026-2074 zipp Denial of Service vulnerability
A Denial of Service DoS vulnerability exists in the jaraco/zipp library, affecting all versions prior to 3.19.1. The vulnerability is triggered when processing a specially crafted zip file that leads to an infinite loop. This issue also impacts the zipfile module of CPython, as features from the...
PYSEC-2026-1081 Aim denial of service vulnerability
A vulnerability in aimhubio/aim version 3.19.3 allows an attacker to cause an infinite loop by configuring the remote tracking server to point at itself. This results in the server endlessly connecting to itself, rendering it unable to respond to other connections...
golang.org/x/crypto/ssh: golang.org/x/crypto/ssh: Denial of Service via resource leak from unsolicited SSH responses
A flaw was found in golang.org/x/crypto/ssh. A remote malicious SSH peer can exploit this by sending unsolicited global request responses, which fills an internal buffer and blocks the connection's read loop. This prevents the associated resources from being released, leading to a resource leak p...
