Description

c-ares is an asynchronous resolver library. Prior to 1.34.7, ares_dns_name_parse() enforces backward DNS compression pointers but does not bound the total pointer hops or assembled name length. A malicious DNS server can send a response containing a long descending pointer chain and many resource records whose NAME or RDATA fields refer to the chain, causing repeated decompression work that grows quadratically with message size. A single crafted response can stall the single-threaded c-ares event loop and deny DNS resolution, without causing memory corruption or information disclosure. This issue is fixed in version 1.34.7.

CVE-2026-93455

django-page-cms through version 2.0.13 contains an authorization bypass vulnerability in its admin helper views. The flaw allows low-privilege staff accounts to read unpublished drafts, page listings, and stored media paths without proper permission validation. This matters because it exposes sensitive organizational content to internal users who should not have access.

CVE-2026-52727

The lxc-ci project inadvertently included a static pacman local-signing private key within Arch Linux container and virtual machine images built prior to May 28, 2026. This allows a malicious or compromised package mirror to issue cryptographically trusted packages to clients. Consequently, attackers can achieve arbitrary code execution as root on affected systems.

CVE-2026-81505

Convoy is a cloud native webhooks gateway. Prior to 26.6.8, Convoy's GET /api/v1/projects/{projectID}/sources/{sourceID} endpoint authorizes access to the project in the URL, but Handler.GetSource calls sources.Service.FindSourceByID() and fetches the Source only by sourceID without confirming that its ProjectID matches the authorized project. An authenticated user or project-scoped API key holder can substitute another tenant's Source identifier and receive that Source's complete record, including unredacted AMQP, Kafka, SQS, or Google PubSub credentials. The list endpoint remains project-scoped; the single-item Source lookup is affected. This issue is fixed in version 26.6.8.

CVE-2026-91149

A flaw was found in Cockpit. An unauthenticated remote attacker can exploit this vulnerability by initiating and sustaining numerous simultaneous connections to the `cockpit-tls` service. This forces the service to create an unbounded number of detached threads, consuming system resources such as memory and file descriptors. The primary consequence is a denial of service (DoS), leading to degradation or complete unavailability of the Cockpit service for legitimate users.
