CVE-2026-81096 Aug 27, 14:50 CRITICAL Act Now

Unauthenticated remote code execution affects mims-harvard ToolUniverse through 1.2.6, where the python_code_executor tool runs caller-supplied Python in a sandbox that can be escaped and the HTTP/MCP servers listen on all interfaces with no authentication. Any attacker who can reach the exposed port executes arbitrary code as the server process, since the deny-list source inspection can be bypassed via dunder attribute traversal and a per-call flag that widens the import allow-list. No public exploit code is identified at time of analysis, but the flaw is reported by VulnCheck and carries a CVSS 4.0 base score of 9.3; it is fixed in version 1.3.0.

Missing authentication on the mcp-router CLI's MCP aggregator exposes every backend MCP server it fronts to any network-reachable attacker. In releases before 0.6.3, the `serve` command bound to the all-interfaces address (0.0.0.0) on fixed port 3283 by default and only enforced a token when the operator explicitly passed the `--token` flag, so a normal `mcpr-cli serve ...` invocation published the aggregator unauthenticated to the entire network.

CVE-2026-79988 Aug 27, 15:36 HIGH PATCH This Week

Remote code execution in Craft CMS allows authenticated users with Twig template access to escape the sandbox via permissive Yii framework functionality, achieving full confidentiality, integrity, and availability compromise on the host system. The root cause is CWE-693 (Protection Mechanism Failure): the Twig sandbox policy was configured to permit dangerous Yii framework methods capable of executing arbitrary code, rather than enforcing a tight allowlist. The vendor confirmed and patched this as a high-severity RCE in release 5.10.7; no public exploit code has been confirmed at time of analysis, though a Hackrate hacktivity report exists referencing the issue.

CVE-2026-13108 Aug 27, 23:26 HIGH PATCH This Week

WatchGuard Dimension's log listening service can be rendered unavailable by an unauthenticated remote attacker flooding it with TCP SYN packets, a classic resource exhaustion denial-of-service technique. The CVSS 4.0 base score of 8.7 reflects high availability impact with no authentication, no user interaction, and no configuration prerequisite required. No public exploit code has been identified and this CVE does not appear in the CISA KEV catalog at time of analysis.

CVE-2026-47879 Aug 27, 06:17 HIGH This Week

Server-side request forgery (SSRF) in Spring Cloud Gateway's JsonToGrpcGatewayFilterFactory allows an authenticated gateway administrator to specify arbitrary Spring Resource URLs as the proto descriptor location, causing the gateway to fetch attacker-controlled internal or external resources. Affected versions span the 3.x through 5.x release trains (CPE: cpe:2.3:a:vmware:spring_cloud_gateway). A successful exploit enables the gateway host to be weaponized as an HTTP pivot into internal network services, with confidentiality and integrity impact on systems beyond the gateway boundary (S:C). No public exploit or active exploitation has been identified at time of analysis.

CVE-2026-81687 Aug 27, 14:50 HIGH PATCH This Week

Unbounded KDF iteration processing in jahlives/openssl_encrypt before 1.4.9 allows remote unauthenticated attackers to trigger sustained CPU exhaustion by supplying crafted files whose metadata contains arbitrarily high key derivation function iteration counts. Because the library reads this attacker-controlled value from file metadata and begins key derivation without enforcing any upper time or iteration ceiling, authentication can be held hostage indefinitely, starving the host of CPU resources. No public exploit has been identified at time of analysis, though the AV:N/PR:N/UI:N CVSS profile means any service that accepts encrypted file uploads from untrusted parties is exposed without prerequisite access.

CVE-2026-81704 Aug 27, 14:51 HIGH PATCH This Week

Weak key derivation in openssl_encrypt before 1.4.9 exposes all files encrypted via the D-Bus CryptoService.EncryptFile handler to accelerated offline password guessing attacks that shatter the tool's documented confidentiality guarantees. The handler uses a single-pass SHA-256 hash for key derivation instead of a memory-hard algorithm such as Argon2id, enabling any attacker who obtains an encrypted file to crack the password six to seven orders of magnitude faster than the product implies. No public exploit code or active exploitation has been identified at time of analysis, though the weakness is structurally trivial to exploit with commodity GPU cracking tooling.

CVE-2026-81691 Aug 27, 14:50 HIGH PATCH This Week

Cleartext credential interception in jahlives/openssl_encrypt before 1.4.9 exposes client_id values, passwords, and JWTs to network-path attackers through the login and register_with_email functions. The library accepts unencrypted http:// URLs and unconfigured host values without validation, transmitting authentication material in cleartext to keyservers and enabling full keyserver account takeover. No active exploitation has been confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis, though the network-accessible nature with no required privileges makes credential interception straightforward for anyone positioned on the traffic path.

CVE-2026-81689 Aug 27, 14:50 HIGH PATCH This Week

Weak pepper wrap key derivation in openssl_encrypt (versions before 1.4.9) allows fleet-wide offline password recovery against all users from a single precomputed dictionary table. The library derives its remote-pepper wrap key using unsalted HKDF-SHA256 or bare SHA-256 of the password, producing identical wrap keys across every user and every file - eliminating the per-user randomness that salting is designed to provide. Any attacker who obtains wrapped pepper blobs can precompute one lookup table and attack the entire user population at GPU-limited speed. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.

CVE-2026-81688 Aug 27, 14:50 HIGH PATCH This Week

openssl_encrypt by jahlives (versions before 1.4.9) embeds an unkeyed SHA-256 digest of each plaintext document into the encrypted file's cleartext header, creating a passive plaintext-confirmation oracle. Any party who possesses an encrypted file - including unauthorized recipients of intercepted or leaked archives - can extract this hash without the encryption password and use it to verify guessed or known plaintexts via offline dictionary attacks. Additionally, because the hash is unkeyed and deterministic, identical source documents encrypted separately under different passwords produce matching header hashes, enabling cross-file correlation and fingerprinting that undermines the confidentiality guarantees users expect from file encryption. No public exploit code has been identified at time of analysis, and this vulnerability does not appear in CISA KEV.

CVE-2026-78612 Aug 27, 23:26 HIGH PATCH This Week

Authenticated SQL injection in WatchGuard Dimension's scheduled report feature permits arbitrary OS command execution as the Dimension WebUI process user. All versions of the product are listed as potentially affected per CPE data, with exploitation requiring a valid session holding report administration permissions. No public exploit code or CISA KEV listing has been identified at time of analysis, though the post-authentication command execution capability represents a critical risk for any deployment where report admin credentials can be obtained.

CVE-2026-78614 Aug 27, 23:26 HIGH PATCH This Week

Authenticated SQL injection in WatchGuard Dimension's audit report feature enables privilege escalation to arbitrary OS command execution, running as the Dimension WebUI process account. The vulnerability is exploitable by any user holding report administration permissions, making it a significant lateral-movement and post-compromise pivot risk within WatchGuard-managed network environments. No public exploit code or CISA KEV listing has been identified at time of analysis, though the chained SQL injection-to-command-execution primitive is high impact for attackers who have obtained admin-level credentials.

CVE-2026-81716 Aug 27, 14:51 HIGH PATCH This Week

Path traversal in the openssl-encrypt pip package (versions before 1.4.9) enables a sandboxed plugin to escape its intended isolation and access or modify a sibling plugin's files when the two plugin directories share a name prefix. The flaw in PluginSandbox._is_safe_path performs a bare string-prefix match rather than an exact directory boundary comparison, so a plugin allowed under .../plugins/foo incorrectly passes the safety check for .../plugins/foobar. Vendor-released patch version 1.4.9 corrects the flaw; no public exploit code has been identified and the package is absent from the CISA KEV catalog.
