CVE-2026-20125
HighSummary
Podatność w funkcji serwera HTTP oprogramowania Cisco IOS i Cisco IOS XE w wersji 3E może pozwolić uwierzytelnionemu, zdalnemu atakującemu na nieoczekiwane przeładowanie urządzenia, co prowadzi do stanu odmowy usługi (DoS). Problem wynika z niewłaściwej walidacji danych wejściowych dostarczonych przez użytkownika.
Risk Assessment
Organizacja może doświadczyć przerw w dostępności usług, co może prowadzić do zakłóceń w działalności oraz potencjalnych strat finansowych. Atakujący musi posiadać ważne konto użytkownika, aby móc wykorzystać tę podatność.
Recommendation
Zaleca się monitorowanie i ograniczenie dostępu do funkcji serwera HTTP oraz regularne aktualizowanie oprogramowania Cisco do najnowszych wersji, aby zminimalizować ryzyko wykorzystania tej podatności.

- CVE-2026-61534Critical
In the Yayson library for serializing and reading JSON API data in JavaScript, prior to 4.3.0, Store and LegacyStore use attacker-controlled JSON:API type, id, and relationship names as keys in plain-object lookup tables. A document whose type is __proto__ causes model-cache writes to modify Object.prototype, with the attacker controlling the polluted property name through id and its value through attributes. This can result in process-wide prototype pollution, causing denial of service and logic corruption.
- CVE-2026-57145Critical
In PraisonAI, a multi-agent teams system, prior to 4.6.62, src/praisonai/praisonai/tools/multiedit.py passes the LLM-controlled filepath parameter directly to open for reading and writing without traversal rejection, symlink resolution, a workspace boundary, or protected-path checks. Prompt-influenced agents can read or overwrite files.
- CVE-2026-57131Critical
In PraisonAI, a multi-agent teams system, prior to 4.6.58, praisonai.jobs.server.create_app mounts praisonai.jobs.router.create_router under /api/v1/runs without authentication or per-job authorization. Network clients can submit attacker-controlled prompts and agent configuration, list and read jobs, stream results, and cancel or delete other jobs.
- CVE-2026-90961Critical
The LdapAuth and LinOTPAuth plugins in MISP contain an authentication bypass vulnerability. Missing input validation allows empty or non-string credentials to reach authentication logic, leading to unauthenticated LDAP binds (RFC 4513) or acceptance of empty passwords. This can allow an attacker to impersonate any known user without a password.
- CVE-2026-90898Critical
Bifrost registers MCP clients through its management API, where a stdio client is a command plus args that is started immediately upon client addition, with no MCP handshake required. Authentication is disabled by default (governance.auth_config.is_enabled=false), meaning every caller is treated as a local admin. A single unauthenticated POST /api/mcp/client is enough to run a program as the Bifrost process user (appuser on the official image).
Original NVD description (English source)
A vulnerability in the HTTP Server feature of Cisco IOS Software and Cisco IOS XE Software Release 3E could allow an authenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending malformed HTTP requests to an affected device. A successful exploit could allow the attacker to cause a watchdog timer to expire and the device to reload, resulting in a DoS condition. To exploit this vulnerability, the attacker must have a valid user account.
