CVE-2026-7439 WRITEUP MEDIUM WRITEUP
AgentFlow Local Web API Content-Type Validation Bypass
AgentFlow's local web API accepts non-JSON content types on POST /api/runs and POST /api/runs/validate endpoints without enforcing application/json validation, allowing attackers to bypass trust-boundary enforcement on sensitive operations. Attackers can exploit this content-type validation weakness through browser-driven or local cross-origin requests to abuse the localhost API and enable attack chains against the local control plane.
CVSS 4.4
CVE-2026-6941 WRITEUP MEDIUM WRITEUP
radare2 < 6.1.4 Project Notes Path Traversal via Symlink
radare2 prior to 6.1.4 contains a path traversal vulnerability in its project notes handling that allows attackers to read or write files outside the configured project directory by importing a malicious .zrp archive containing a symlinked notes.txt file. Attackers can craft a .zrp archive with a symlinked notes.txt that bypasses directory confinement checks, allowing note operations to follow the symlink and access arbitrary files outside the dir.projects root directory.
CVSS 6.6
CVE-2026-6819 WRITEUP HIGH WRITEUP
HKUDS OpenHarness Plugin Management Command Exposure
HKUDS OpenHarness prior to PR #156 remediation exposes plugin lifecycle commands including /plugin install, /plugin enable, /plugin disable, and /reload-plugins to remote senders by default. Attackers who gain access through the channel layer can remotely manage plugin trust and activation state, enabling unauthorized plugin installation and activation on the system.
CVSS 8.8
CVE-2026-6823 WRITEUP HIGH WRITEUP
HKUDS OpenHarness Insecure Default Remote Channel Allowlist
HKUDS OpenHarness prior to PR #147 remediation contains an insecure default configuration vulnerability where remote channels inherit allow_from = ["*"] permitting arbitrary remote senders to pass admission checks. Attackers who can reach the configured channel can bypass access controls and reach host-backed agent runtimes, potentially leading to unauthorized file disclosure and read access through default-enabled read-only tools.
CVSS 8.2
CVE-2026-6830 WRITEUP LOW WRITEUP
Nesquena Hermes WebUI Environment Variable Credential Leakage via Profile Switch
nesquena hermes-webui contains an environment variable leakage vulnerability where profile switching does not clear environment variables from the previously active profile before loading the next profile. Attackers or users can exploit additive dotenv reload behavior to access provider API keys and other sensitive secrets from one profile context in another profile, breaking expected security isolation between profiles.
CVSS 3.3
CVE-2026-6729 WRITEUP MEDIUM WRITEUP
HKUDS OpenHarness Session Key Collision Privilege Escalation
HKUDS OpenHarness prior to PR #159 remediation contains a session key derivation vulnerability that allows authenticated participants in shared chats or threads to hijack other users' sessions by exploiting a shared ohmo session key that lacks sender identity verification. Attackers can reuse another user's conversation state and replace or interrupt their active tasks by colliding into the same session boundary through the shared chat or thread scope.
CVSS 6.3
CVE-2026-40525 WRITEUP CRITICAL WRITEUP
OpenViking Authentication Bypass via VikingBot OpenAPI
OpenViking prior to version 0.3.9 contains an authentication bypass vulnerability in the VikingBot OpenAPI HTTP route surface where the authentication check fails open when the api_key configuration value is unset or empty. Remote attackers with network access to the exposed service can invoke privileged bot-control functionality without providing a valid X-API-Key header, including submitting attacker-controlled prompts, creating or using bot sessions, and accessing downstream tools, integrations, secrets, or data accessible to the bot.
CVSS 9.1
CVE-2026-40518 WRITEUP HIGH WRITEUP
ByteDance DeerFlow Path Traversal and Arbitrary File Write via Bootstrap Mode
ByteDance DeerFlow before commit 2176b2b contains a path traversal and arbitrary file write vulnerability in bootstrap-mode custom-agent creation where the agent name validation is bypassed. Attackers can supply traversal-style values or absolute paths as the agent name to influence directory creation and write files outside the intended custom-agent directory, potentially achieving arbitrary file write on the system subject to filesystem permissions.
CVSS 7.1
CVE-2026-40502 WRITEUP HIGH WRITEUP
OpenHarness Remote Administrative Command Injection via Gateway Handler
OpenHarness prior to commit dd1d235 contains a command injection vulnerability that allows remote gateway users with chat access to invoke sensitive administrative commands by exploiting insufficient distinction between local-only and remote-safe commands in the gateway handler. Attackers can execute administrative commands such as /permissions full_auto through remote chat sessions to change permission modes of a running OpenHarness instance without operator authorization.
CVSS 8.8
CVE-2026-40503 WRITEUP MEDIUM WRITEUP
OpenHarness Path Traversal Information Disclosure via /memory show
OpenHarness prior to commit dd1d235 contains a path traversal vulnerability that allows remote gateway users with chat access to read arbitrary files by supplying path traversal sequences to the /memory show slash command. Attackers can manipulate the path input parameter to escape the project memory directory and access sensitive files accessible to the OpenHarness process without filesystem containment validation.
