Technical description

A Missing Authentication for Critical Function vulnerability in command processing of Juniper Networks Junos OS allows a privileged local attacker to gain access to Linux-based line cards as root. This issue affects systems running Junos OS using Linux-based line cards. Affected line cards include: * MPC7, MPC8, MPC9, MPC10, MPC11 * LC2101, LC2103 * LC480, LC4800, LC9600 * MX304 (built-in FPC) * MX-SPC3 * SRX5K-SPC3 * EX9200-40XS * FPC3-PTX-U2, FPC3-PTX-U3 * FPC3-SFF-PTX * LC1101, LC1102, LC1104, LC1105 This issue affects Junos OS: * all versions before 22.4R3-S8, * from 23.2 before 23.2R2-S6, * from 23.4 before 23.4R2-S6, * from 24.2 before 24.2R2-S3, * from 24.4 before 24.4R2, * from 25.2 before 25.2R2.

——7lakeFS through 1.83.0, fixed in commit 71a45ee, contains an authentication bypass vulnerability in the /setup_comm_prefs endpoint that allows unauthenticated attackers to overwrite operator metadata including email, name, and company after setup completion. Attackers can POST to this endpoint to modify security update preferences, disable security communications, and trigger falsified telemetry events using the legitimate installation ID.2d CVE-2026-5616310.0 CRI

——9APIFold reads an OpenAPI 3.x or Swagger 2.x specification and generates a live, production-ready MCP server endpoint. Prior to commit 7f19b52280f414f57af2b79a95333d1c8fbeece5, the `/webhooks/:serverSlug/:eventName` endpoint accepts arbitrary unauthenticated JSON and stores it in Redis and the `webhook_events` PostgreSQL table without any signature check or authentication requirement. The root cause is that `createWebhookRouter` is called at `server.ts:188` without a `validators` map, so `receivers.ts:80`'s optional-chaining guard evaluates to `undefined` and the signature-validation block (`receiver.ts:81–95`) is unconditionally skipped. Any unauthenticated network client that knows a valid server slug can inject arbitrary payloads, which are subsequently served as trusted resource state to legitimate MCP clients. Commit 7f19b52280f414f57af2b79a95333d1c8fbeece5 patches the issue.3d CVE-2026-6481210.0 CRI
