CVE-2026-92982 Alta · 8.5 CWE-1336 15/10/2026

Ansible-operator-plugins: ansible operator plugins: arbitrary code execution via jinja2 template injection

A flaw was found in Ansible Operator Plugins. A low-privileged Kubernetes user can exploit a Jinja2 template injection vulnerability by crafting malicious custom resource (CR) specification values. These values are processed by Ansible without proper sanitization, allowing embedded Jinja2 expressions to be executed within the operator pod. This can lead to arbitrary code execution and privilege escalation, granting the attacker control over the operator's service account with cluster-wide permissions.

Jwcrypto: jwcrypto: denial of service via o(n^2) duplicate check on unbounded jwk key_ops array

A flaw was found in jwcrypto. The JWK.import_key() function validates the key_ops JWK member for duplicate values using an algorithm with O(n^2) time complexity, and the length of key_ops is not bounded. A remote, unauthenticated attacker can supply a JWK with a large key_ops array to an application that passes attacker-controlled key material to a public key-import API (reachable via ECDH-ES key agreement, OIDC dynamic client registration, DPoP, or ACME account key registration, among others) to consume excessive CPU time, resulting in a denial of service.

CVE-2026-84828 Média · 6.5 CWE-732 10/09/2026

Pcs: pcs: non-root haclient users can read arbitrary files via pcs host auth --token

A flaw was found in PCS (Pacemaker Configuration System). A local attacker with membership in the 'haclient' group can exploit the 'pcs host auth --token' command to read the contents of arbitrary files on the filesystem, provided the files are shorter than 256 bytes. The file contents are read with root privileges by the pcsd daemon and can be exfiltrated by the attacker through subsequent cluster node communication. This allows disclosure of sensitive data such as API keys, tokens, or configuration secrets that would otherwise be inaccessible to the attacker.

CVE-2026-80179 Média · 5.9 CWE-770 27/08/2026

Jwcrypto: jwcrypto: denial of service via malformed jwe tokens

A flaw was found in jwcrypto. A remote attacker can send a specially crafted JSON Web Encryption (JWE) token containing numerous period delimiters. This malformed token can force the JWE.deserialize() function to allocate excessive memory, leading to a MemoryError. This issue results in a denial of service (DoS) for services that process untrusted JWE values.

CVE-2026-34956 Média · 5.9 CWE-120 05/05/2026

Openvswitch: open vswitch: denial of service via malformed ftp epasv command

A flaw was found in Open vSwitch. When Open vSwitch is configured with a conntrack flow using FTP helpers over the userspace datapath, a remote attacker can send a specially crafted FTP stream with an EPASV command exceeding 255 characters. This heap access error can lead to a crash, resulting in a Denial of Service (DoS) for the affected system.

CVE-2021-4472 Média · 6.5 CWE-73 26/11/2025

Python-mistralclient: mistral-dashboard: local file inclusion through the 'create workbook' feature

The mistral-dashboard plugin for openstack has a local file inclusion vulnerability through the 'Create Workbook' feature that may result in disclosure of arbitrary local files content.

CVE-2024-3727 Alta · 8.3 CWE-354 14/05/2024

Containers/image: digest type does not guarantee valid type

A flaw was found in the github.com/containers/image library. This flaw allows attackers to trigger unexpected authenticated registry accesses on behalf of a victim user, causing resource exhaustion, local path traversal, and other attacks.

CVE-2024-1394 Alta · 7.5 CWE-401 21/03/2024

Golang-fips/openssl: memory leaks in code encrypting and decrypting rsa payloads

A memory leak flaw was found in Golang in the RSA encrypting/decrypting code, which might lead to a resource exhaustion vulnerability using attacker-controlled inputs. The memory leak happens in github.com/golang-fips/openssl/openssl/rsa.go#L113. The objects leaked are pkey and ctx. That function uses named return parameters to free pkey and ctx if there is an error initializing the context or setting the different properties. All return statements related to error cases follow the "return nil, nil, fail(...)" pattern, meaning that pkey and ctx will be nil inside the deferred function that should free them.
