BIT-GHOST-2026-53945 Ghost: Server-side request forgery via DNS rebinding in external request handling

Ghost is a Node.js content management system. From 6.0.9 until 6.21.1, Ghost’s private-IP check for outbound HTTP requests could be bypassed via DNS rebinding, allowing an attacker to coerce the Ghost server into reaching hosts on internal networks through features that issue external fetches. Th...

CVE-2026-54898

Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.2,Oj::Parserparse is vulnerable to a heap use-after-free when a SAJ/SAJ2 callback mutates the input JSON string during parsing. The C engine holds a raw const byte pointer into the Ruby...

DEBIAN-CVE-2026-54696

Ruby JSON is a JSON implementation for Ruby. Versions 2.9.0 through 2.19.8 are vulnerable to heap buffer overflow when the JSON generator is provided with an oversized streamed object. When streaming to an IO JSON.dumpobj, io and JSON::Stategenerateobj, io can write past the internal JSON generat...

CVE-2026-54592

The CVE-2026-54592 vulnerability affects Oj (Optimized JSON), a Ruby gem JSON parser/marshaller. In versions prior to 3.17.3, Oj::Doc#each_child can overflow a fixed-size stack buffer when recursively traversing deeply nested JSON, causing a DoS. The issue arises from a two-step chain in ext/oj/f...

CVE-2026-54500 Oj: intern.c form_attr has an uninitialized stack read

Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.3, Oj.load in :object mode reads uninitialized stack memory and, for long keys, reads out of bounds when parsing a JSON object whose key is 254 bytes or longer. The interned bytes can surfac...

UBUNTU-CVE-2026-57204

pypdf is a free and open-source pure-python PDF library. Prior to 6.13.3, a maliciously crafted PDF can cause DoS. An attacker who uses this vulnerability can craft a PDF which leads to large memory usage, as MAXDECLAREDSTREAMLENGTH is sometimes ignored. This requires parsing a content stream...

UBUNTU-CVE-2026-57585

MessagePack is the serializer implementation for Python msgpack.org. Prior to 1.2.1, there is an Out-of-bounds read/crash on Unpacker reuse after a caught error, potentially leading to a DoS attack. If the Unpacker is used repeatedly after an error occurs, the process may crash with a SEGV. This...

Fission: Cross-namespace event leakage via KubernetesWatchTrigger allows persistent tenant surveillance

Summary A low-privilege developer who could create a KubernetesWatchTrigger KWT in their own namespace was able to establish a persistent surveillance channel over any other namespace. Details Two independent flaws compounded: 1. pkg/kubewatcher/kubewatcher.go::createKubernetesWatch used...

CVE-2026-27957

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, an authenticated command injection vulnerability in the CA Certificate management feature allows any authenticated user to execute arbitrary commands as the configured SSH...

CVE-2026-27881 Coolify: Cross-team deployment information disclosure via GET /api/v1/deployments/{uuid} (IDOR)

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, GET /api/v1/deployments/uuid in DeployController.php retrieves deployment details without validating that the deployment belongs to the authenticated user's team. Any...

CVE-2026-53433

In fzf, CVE-2026-53433, the DoS arises from inefficient HTTP body processing in the --listen mode due to repeated string concatenation, giving quadratic time (O(n²)) for a crafted POST request with many small segments. This can cause a single malicious request to monopolize the single-threaded HT...

CVE-2026-53432

CVE-2026-53432 (fzf) affects the fzf project, specifically the FuzzyMatchV2 function. Affected scenario involves processing extremely long input lines (≈2,200,000 bytes) with a pattern length of 999 bytes, which causes an integer overflow and triggers a non-recoverable panic, terminating the proc...
