PYSEC-2026-3626 aiosend: Deserialization of request body before signature verification (Pre-auth DoS) in webhook handler

Summary WebhookHandler.feedupdate deserializes the entire request body before verifying the HMAC signature. This allows an unauthenticated attacker to force expensive parsing of arbitrary JSON payloads that will ultimately be rejected, leading to unnecessary CPU and memory consumption. Severity...

brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity

A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the expand function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-lo...

PT-2026-76487

Impact An attacker who uses this vulnerability can craft a PDF which leads to large memory consumption. This requires parsing the /ToUnicode entry of a font with unusually large values, for example during text extraction. Patches This has been fixed in pypdf==6.15.0. Workarounds If you cannot...

PT-2026-80481

A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to...

CVE-2026-72914: Asymmetric Resource Consumption (Amplification)

Mastodon is a free, open-source social network server based on ActivityPub. Prior to 4.4.21, 4.5.14, 4.6.4, and 4.7.0-beta.1, the administrative statistics endpoints handled by Api::V1::Admin::MeasuresController and Api::V1::Admin::RetentionController checked authorization only after beginning...

Audio/Video Component DoS

The vulnerability of the Audio/Video component: Playback in Firefox web browser and Thunderbird email client involves an uncontrolled consumption of resources. Exploiting this vulnerability can allow a remote attacker to cause service interruptions...

CVE-2026-18503: Inefficient CPU Computation

Attacker-controlled CSV samples can trigger super-linear regular-expression work during dialect sniffing and consume significant CPU when applications pass unbounded input to csv.Sniffer.sniff...

CVE-2026-72912: Uncontrolled Resource Consumption

CyberChef is a web app for encryption, encoding, compression, and data analysis. Prior to 11.3.0, CyberChef's pretty-recipe parser in src/core/Utils.mjs can exhaust client-side CPU when a malformed recipe= URL fragment containing a large number of unmatched quote characters reaches...

CVE-2026-69659 Memory exhaustion via unbounded deserialization of keyset pagination cursors in Ash.Page.Keyset

Uncontrolled Resource Consumption vulnerability in ash-project ash allows an attacker to exhaust the memory of the node via a crafted keyset pagination cursor. Read actions with keyset pagination deserialize the client-supplied page:after or page:before cursor in decodevalues/2 in...
