CVE-2026-55997 Long-lived Rancher registration token exposed in plaintext

Rancher issues long-lived registration tokens to authenticate nodes and agents joining a downstream cluster. These tokens were stored and exposed in plaintext with no expiration, so a malicious user could obtain one either through the Rancher API, etcd, stored automation, or direct file access on...

CVE-2026-45809

OpenSIPS is a Session Initiation Protocol SIP server implementation. Versions prior to 3.6.6 and 4.0.0-rc1 contain a denial of service vulnerability in the watcherinfo generation functionality. An attacker can create an oversized watcher entry by sending a SUBSCRIBE Event: presence request with a...

CVE-2026-45537

OpenSIPS is a Session Initiation Protocol SIP server implementation. In versions prior to 3.6.6 and 4.0.0-rc1, the constructuri function concatenates multiple URI components protocol, username, domain, port, params into a fixed 1024-byte global BSS buffer without any bounds checking. When a routi...

CVE-2026-45537

OpenSIPS contains a buffer overflow in construct_uri() used to assemble SIP URIs. In versions before 3.6.6 and 4.0.0-rc1, components (protocol, username, domain, port, params) are concatenated into a fixed 1024-byte global BSS buffer without bounds checks. If a routing script supplies a long, att...

CVE-2026-45538

OpenSIPS is a Session Initiation Protocol SIP server implementation. In versions 4.0.0 and prior, processing a SIP message with a header name longer than 255 bytes causes a stack buffer overflow when siptojson is called in the routing script. Function siptojson modules/sipmsgops/sipmsgops.c copie...

Memory Allocation with Excessive Size Value

Overview Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value via the checkforlanguage function. An attacker can exhaust system memory by submittin...

net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME

A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...

CVE-2026-18401

The CVE describes a vulnerability in jackson-core’s non-blocking (async) JSON parser where maxNumberLength is not enforced, unlike the synchronous parser. Root cause: the async parsing path in NonBlockingUtf8JsonParserBase does not invoke number length validation; _finishNumberIntegralPart() accu...

pypdf: Possible long runtimes for repeated malformed cross-reference entries

ImpactAn attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires cross-reference streams with repeated malformed cross-reference streams. PatchesThis has been fixed in pypdf==6.14.0. WorkaroundsIf you cannot upgrade yet, consider applying the changes from ...
