PT-2026-56546

Name of the Vulnerable Software and Affected Versions pypdf versions prior to 6.14.2 Description An attacker can craft a PDF file with a page content stream containing an unterminated inline image that utilizes ASCII85 or ASCIIHex filters. This leads to an infinite loop during the parsing process...

PT-2026-56547

Name of the Vulnerable Software and Affected Versions pypdf versions prior to 6.14.1 Description An attacker can craft a PDF file with a page content stream containing an unterminated inline image. This leads to an infinite loop during the detection of the inline image end marker, which can occur...

ImageMagick IPTCTEXT DoS

The vulnerability of the IPTCTEXT mechanism in the console-based ImageMagick graphic editor is related to the execution of a loop with an unavailable exit condition. Exploiting this vulnerability can allow a remote attacker to cause service interruptions...

ImageMagick JPEG Encoder DoS

The vulnerability of the JPEG encoder in console-based image editing software ImageMagick relates to the execution of a loop with an unavailable exit condition. Exploiting this vulnerability can allow a malicious actor to cause service failures using a specially created image...

AIOHTTP vulnerable to DoS when bypassing asserts

SummaryWhen assert statements are bypassed, an infinite loop can occur, resulting in a DoS attack when processing a POST body. ImpactIf 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 execu...

InvokeAI has Denial of Service (DoS) vulnerability in `/api/v1/images/upload`

A Denial of Service DoS vulnerability in the multipart request boundary processing mechanism of the Invoke-AI server version v5.0.1 allows unauthenticated attackers to cause excessive resource consumption. The server fails to handle excessive characters appended to the end of multipart boundaries...

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-2026-1290 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...

Denial of service (DoS) via deformation `multipart/form-data` boundary

SummaryWhen parsing form data, python-multipart skips line breaks CR \r or LF \n in front of the first boundary and any tailing bytes after the last boundary. This happens one byte at a time and emits a log event each time, which may cause excessive logging for certain inputs.An attacker could...

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...
