Unbounded recursion in Pillow when parsing PDF page trees or trailer chains can cause severe CPU and memory exhaustion or crashes during PDF append operations.
An issue in Pillow allows a maliciously crafted GIF to cause excessive memory allocation when an application handles decompression errors during frame seeking and reuses the image object. This can lead to memory exhaustion and denial of service.
Pillow is vulnerable to an out-of-bounds write when processing zero-width PPM or PGM images during morphology operations. Opening a specially crafted image can cause an application crash and potential memory corruption.
An out-of-bounds read vulnerability in Pillow's tiled-TIFF decoder can allow a specially crafted TIFF image to crash the process or expose adjacent heap memory into the decoded pixel buffer.
An overflow in aiohttp during Max-Age processing can prevent connections from closing properly, allowing an attacker to temporarily exhaust the connector pool until garbage collection runs.
In AIOHTTP, attackers sending absolute-form HTTP requests can spoof the request scheme. If an application relies on the scheme for security checks, attackers may bypass security logic by making unencrypted connections appear encrypted or vice versa.
A vulnerability in aiohttp allows a subdomain to remove the Host-Only flag from existing parent domain cookies, potentially weakening cookie scoping protections.
A denial-of-service vulnerability in markdown-it allows remote attackers to block the Node.js event loop via crafted multi-line link reference definitions. Processing unclosed definitions causes quadratic execution time under default configurations.
A URL parsing discrepancy in the Angular HTTP client can cause cross-site request forgery tokens to leak to external domains during mutating requests. Attackers can leverage these leaked tokens to execute unauthorized actions against an authenticated user session.
In affected versions of the MCP TypeScript SDK, an unauthenticated HTTP request within default size limits can exhaust server memory during validation. This allows attackers to crash the server process through denial of service.
When HTML is enabled in markdown-it, parsing repeated unterminated HTML constructs takes quadratic time. This allows crafted input to block the Node.js event loop and lead to denial of service.
A vulnerability in the MCP TypeScript server SDK causes messages and notifications to be delivered to the wrong HTTP client when server or transport instances are shared, leading to data exposure.
A vulnerability in launch-editor allows attackers to bypass file existence checks on Windows using a specially crafted path. When combined with argument escaping issues, this can lead to operating system command injection if an attacker controls the file path.
A vulnerability in the MCP TypeScript SDK allows servers using bearer authentication to accept tokens issued for other services when sharing an authorization server. Attackers could potentially reuse valid tokens across services to gain unauthorized access unless audience validation is explicitly configured.
The pure-Python parser in aiohttp is vulnerable to HTTP request smuggling when running without standard C extensions. Applications can resolve this issue by updating aiohttp or switching to the default C parser.
A vulnerability in AIOHTTP allows attackers to exhaust file descriptors using specially crafted multipart requests. This can lead to resource exhaustion and potential denial of service.
Default trust stores in affected uv versions trust a root CA with compromised intermediate CA keys. An attacker with access to these compromised keys could forge certificates for arbitrary hostnames, allowing man-in-the-middle attacks on TLS traffic.
Certain certifi releases bundled a root certificate with compromised intermediate keys. An attacker on the network path could issue forged certificates for any hostname and intercept or modify TLS connections.
In affected versions of MCP TypeScript SDK, experimental tasks were not bound to the session that created them. Clients sharing a handler could list, read, and cancel each other's tasks.
ApostropheCMS notification endpoints fail to verify authentication or ownership. An unauthenticated attacker who obtains a valid notification ID can modify or permanently delete another user's notifications.
Under Windows, launch-editor does not properly escape percent signs, allowing potential command execution if an attacker can manipulate filenames, environment variables, or NTFS streams.
In affected versions of the MCP TypeScript client SDK, HTTP client transports and OAuth requests followed cross-origin redirects, potentially exposing custom headers and request bodies to external hosts.
A vulnerability in ApostropheCMS allows the general public to access user objects through relationships if templates expose them, as viewRole is not enforced for unauthenticated public users.
An authorization bypass in the ApostropheCMS page REST API allows unauthenticated visitors and low-privileged contributors to read restricted page content and site structure metadata.
With the DockRay integration and software inventory enabled, DockRay checks reported component versions against known vulnerabilities and notifies you about confirmed matches. Coverage depends on the supported technology and available advisory data.
