Istio: AuthorizationPolicy serviceAccounts regex injection via unescaped dots

Impact The serviceAccounts and notServiceAccounts fields in AuthorizationPolicy incorrectly interpret dots . as a regular expression matcher. Because . is a valid character in a service account name, an AuthorizationPolicy ALLOW rule targeting SA e.g. cert-manager.io also matches cert-manager-io,...

MCP-Framework: Unbounded memory allocation in readRequestBody allows denial of service via HTTP transport

Summary The readRequestBody function in src/transports/http/server.ts concatenates HTTP request body chunks into a string with no size limit, allowing a remote unauthenticated attacker to crash the server via memory exhaustion with a single large HTTP POST request. Details File:...

Summary A stored cross-site scripting XSS vulnerability exists in SEO-related fields SEO Title and Meta Description in ApostropheCMS. Improper neutralization of user-controlled input in SEO-related fields allows injection of arbitrary JavaScript into HTML contexts, resulting in stored cross-site...

SpdyStream: DOS on CRI

The SPDY/3 frame parser in spdystream does not validate attacker-controlled counts and lengths before allocating memory. A remote peer that can send SPDY frames to a service using spdystream can cause the process to allocate gigabytes of memory with a small number of malformed control frames,...

Weblate: Privilege escalation in the user API endpoint

Impact The user patching API endpoint didn't properly limit the scope of edits. Patches https://github.com/WeblateOrg/weblate/pull/18687 References Thanks to @tikket1 and @DavidCarliez for reporting this via GitHub. We received two individual reports for this...

Weblate: SSRF via Project-Level Machinery Configuration

Weblate: Improper access control for pending tasks in API

Impact The API for tasks didn't verify user access for pending tasks. This could expose logs of in-progress operations to users who don't have access to given scope. Patches https://github.com/WeblateOrg/weblate/pull/18515 Workarounds The attacker needs to guess the random UUID of the task, so...

Buffer Overflow in Zlib::GzipReader ungetc via large input leads to memory corruption

Details A buffer overflow vulnerability exists in Zlib::GzipReader. The zstreambufferungets function prepends caller-provided bytes ahead of previously produced output but fails to guarantee the backing Ruby string has enough capacity before the memmove shifts the existing data. This can lead to...

Silverstripe Assets Module has a DBFile::getURL() permission bypass

Impact Images rendered in templates or otherwise accessed via DBFile::getURL or DBFile::getSourceURL incorrectly add an access grant to the current session, which bypasses file permissions. This usually happens when creating an image variant, for example using a manipulation method like ScaleWidt...
