Attackers can inject malicious server blocks to intercept credentials, exfiltrate backend topology, or crash nginx with invalid configs. CVSS 9.8 (Critical) with network attack vector, no authentication required, and high impact across confidentiality, integrity, and availability. No public exploit identified at time of analysis, though detailed proof-of-concept HTTP request provided in advisory.

Remote authenticated attackers can achieve arbitrary command execution on nginx-ui v2.3.3 servers by manipulating encrypted backup archives during restoration. The vulnerability stems from a circular trust model where backup integrity metadata is encrypted using the same AES key provided to clients, allowing attackers to decrypt backups, inject malicious configuration (including command execution directives), recompute valid hashes, and re-encrypt the archive. The restore process accepts tampered backups despite hash verification warnings. Publicly available exploit code exists with detailed proof-of-concept demonstrating configuration injection leading to arbitrary command execution. Vendor-released patch available in nginx-ui v2.3.4. This represents a regression from GHSA-g9w5-qffc-6762, which addressed backup access control but not the underlying cryptographic design flaw.

Exploitation requires an uncommon X.509 topology not typically present in the Web PKI, and no public exploit code or active exploitation has been identified.

Insecure Direct Object Reference (IDOR) in Langflow API allows authenticated users to read, modify, or delete any flow belonging to other users via unvalidated flow_id parameters in GET/PATCH/DELETE /api/v1/flow/{flow_id} endpoints. The vulnerability affects both the langflow and langflow-base Python packages, enabling attackers with valid credentials to exfiltrate sensitive data (including plaintext API keys embedded in flows), tamper with AI agent logic, or destroy other users' workflows. A vendor-released patch (PR #8956) is available. No public exploit code identified at time of analysis, though the vulnerability is straightforward to exploit given the clear description and patch differential in the advisory.

Unauthenticated remote cache poisoning in nektos/act (GitHub Actions local runner) enables arbitrary code execution by exposing the built-in actions/cache server on all network interfaces without authentication. Attackers who can reach the cache server-including from the public internet if exposed-can inject malicious cache entries with predictable keys, leading to remote code execution within Docker containers running GitHub Actions workflows. No public exploit identified at time of analysis, though EPSS data unavailable. Vendor-released patch available in act v0.2.86.

Unauthenticated stream hijacking in LibreChat versions 0.8.2-rc2 through 0.8.2-rc3 allows authenticated users to read other users' real-time chat conversations via the SSE streaming endpoint `/api/agents/chat/stream/:streamId` without ownership verification. An attacker with valid credentials can enumerate or guess stream IDs to intercept sensitive messages, AI-generated responses, and tool invocation data from arbitrary users. The vulnerability was patched in version 0.8.2.

Fleet device management software prior to version 4.81.0 allows privilege escalation through email validation bypass in the user invitation flow. An attacker with a valid invite token can create an account using an arbitrary email address while retaining the role permissions granted by the invite, potentially obtaining global admin access. No public exploit code or active exploitation has been identified at the time of analysis.

Fleet device management software versions prior to 4.81.1 contain a broken access control vulnerability in the host transfer API that allows authenticated team maintainers to transfer hosts from any team into their own team, circumventing team isolation boundaries and gaining full control over stolen hosts including root-level script execution capabilities. The vulnerability requires authenticated access (PR:L in CVSS vector) but presents high integrity impact due to the ability to execute privileged commands on managed endpoints. No public exploit code or active exploitation has been confirmed at time of analysis.

Fleet server memory exhaustion via unbounded request bodies allows unauthenticated denial-of-service against multiple HTTP endpoints. The vulnerability affects Fleet v4 (github.com/fleetdm/fleet/v4) and was responsibly disclosed by @fuzzztf. Attackers can exhaust available memory and force server restarts by sending oversized or repeated HTTP requests to unauthenticated endpoints lacking size limits. No public exploit identified at time of analysis, though the attack mechanism is straightforward given the CWE-770 resource allocation vulnerability class.

Fleet's password reset token invalidation logic fails to revoke previously issued tokens when a user changes their password, allowing attackers with a captured token to perform account takeover by resetting the password again within the token's 24-hour validity window. The vulnerability affects Fleet versions distributed via the Go package github.com/fleetdm/fleet/v4 and requires prior compromise of a valid password reset token to exploit, limiting real-world impact to scenarios where token interception has already occurred.

WWBN AVideo versions up to 26.0 expose all non-private video categories to unauthenticated remote attackers due to missing access control enforcement in the categories.json.php endpoint. The vulnerability combines two distinct flaws: complete bypass of group-based filtering when no user parameter is supplied, and a type confusion bug that substitutes the admin user's group memberships when a user parameter is present, allowing unauthorized disclosure of category metadata intended for restricted user groups. CVSS 5.3 reflects the information disclosure impact with no authentication required and low attack complexity; no public exploit code or active exploitation has been confirmed at time of analysis.

GitHub Actions workflow artifacts in Wazuh version 4.12.0 expose GITHUB_TOKEN credentials that unauthenticated network attackers can extract and use within a limited time window to push malicious commits or alter release tags in the project repository. The vulnerability carries a CVSS 4.0 score of 8.3 with high integrity impact and low availability impact. No public exploit identified at time of analysis, though the vulnerability is classified under authentication bypass tags by VulnCheck.

WWBN AVideo up to version 26.0 fails to enforce password verification on API endpoints `get_api_video_file` and `get_api_video`, allowing unauthenticated remote attackers to retrieve direct playback URLs (MP4 files and HLS manifests) for password-protected videos by directly invoking the API. The web interface enforces password checks through the `CustomizeUser::getModeYouTube()` hook, but this validation is entirely absent from the API code path, creating a complete authentication bypass. Upstream fix available via commit be344206f2f461c034ad2f1c5d8212dd8a52b8c7; no public exploit or active exploitation confirmed at time of analysis.

Prototype pollution in locutus npm package version 2.0.39 through 3.0.24 allows remote attackers to bypass `Object.prototype` pollution guards via a crafted query string passed to the `parse_str` function, enabling authentication bypass, denial of service, or remote code execution in chained attack scenarios where `RegExp.prototype.test` has been previously compromised. Publicly available exploit code exists demonstrating the vulnerability; vendor-released patch available in version 3.0.25.

Authorization bypass in Docker Engine (moby) allows API clients to evade AuthZ plugin policy decisions by issuing requests whose body is not forwarded to the plugin, causing it to approve operations it would otherwise deny. This is an incomplete-fix regression of CVE-2024-41110 affecting deployments that rely on AuthZ plugins inspecting request bodies; publicly available exploit code exists but EPSS is 0.01% and SSVC exploitation status is 'none'.

WWBN AVideo versions up to 26.0 allow authenticated users to arbitrarily overwrite poster images for any scheduled live stream due to missing authorization checks in the uploadPoster.php endpoint, combined with subsequent broadcast of sensitive broadcast keys and user IDs to all connected WebSocket clients. An authenticated attacker can exploit this vulnerability without user interaction to deface another user's scheduled broadcasts and potentially harvest credential material for further attacks. No public exploit identified at time of analysis, though the vulnerability has been disclosed via GitHub security advisory with a published fix commit available.

Broadcast schedule modification in WWBN AVideo versions up to 26.0 allows authenticated users with streaming permissions to hijack playlists and disrupt streams by creating or modifying schedules targeting any playlist regardless of ownership, with rebroadcasts executing under the victim's identity. The vulnerability affects the `plugin/PlayLists/View/Playlists_schedules/add.json.php` endpoint and stems from insufficient authorization checks. Upstream fix available via commit 1e6dc20172de986f60641eb4fdb4090f079ffdce; no public exploit identified at time of analysis.

Appsmith versions prior to 1.98 allow unauthenticated remote attackers to access sensitive instance management API endpoints (/api/v1/consolidated-api/view, /api/v1/tenants/current) without authentication, enabling disclosure of configuration metadata, license information, and unsalted SHA-256 hashes of admin email domains. This authentication bypass facilitates reconnaissance for targeted follow-up attacks against Appsmith deployments and their administrators. No public exploit code or active exploitation has been independently confirmed at time of analysis.

HTTP request smuggling in Undertow allows remote unauthenticated attackers to send `\r\r\r` as a header block terminator, which can desynchronize parsing when Undertow sits behind specific intermediaries such as older Apache Traffic Server or Google Cloud Classic Application Load Balancer. The flaw affects numerous Red Hat distributions of Undertow (JBoss EAP 7/8, Data Grid 8, Fuse 7, Camel for Spring Boot 4, RHEL 8/9/10) and carries a CVSS 9.1, though EPSS is only 0.04% and there is no public exploit identified at time of analysis.

HTTP request smuggling in Red Hat Undertow allows remote unauthenticated attackers to bypass front-end security controls by exploiting parsing discrepancies between Undertow and upstream proxies when handling crafted header names. The flaw (CWE-444) affects Undertow embedded in multiple Red Hat products including JBoss EAP 7/8, Data Grid 8, Fuse 7, and Apache Camel for Spring Boot 4, with Red Hat issuing patches via RHSA-2026:25125 and RHSA-2026:25126. There is no public exploit identified at time of analysis and EPSS is low (0.10%), but CVSS 9.1 and SSVC 'total' technical impact warrant prompt patching of internet-facing deployments.

OpenBMB XAgent 1.0.0 ShareServer WebSocket endpoint allows remote authentication bypass through manipulation of the interaction_id parameter in the check_user function, enabling unauthenticated attackers to access protected resources with low confidentiality, integrity, and availability impact. Publicly available exploit code exists, the vendor was contacted but did not respond, and active exploitation remains possible.
