CVE-2026-109162 (GCVE-0-2026-109162)

Title
TYPO3 CMS - Security Misconfiguration in Form Framework
Summary
Forms using FileUpload or ImageUpload elements with a custom saveToFileMount configured stored uploaded files in the default storage folder 1:/user_upload/ instead of the configured destination. This could cause uploaded files to end up in a publicly accessible storage even though a restricted, non-public storage had been configured. Files stored this way are served directly, without the access checks applied to non-public storages. Forms that use the default value for saveToFileMount are not affected. This issue affects TYPO3 CMS versions 14.0.0-14.3.8.

CVE-2026-105745 (GCVE-0-2026-105745)

Vulnerability from cvelistv5 – Published: 2026-10-05 21:29 – Updated: 2026-10-06 14:48

Title
Docling: Plugin entry points are imported before the allow_external_plugins check
Summary
Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. From 2.27.0 until 2.131.0, Docling plugin factories in docling/models/factories/base_factory.py call load_setuptools_entrypoints() before applying the allow_external_plugins setting, so every module registered in the Docling entry-point group is imported even when external plugins are disabled. An installed third-party or compromised package can therefore execute import-time code when Docling starts, while the subsequent namespace filter misleadingly reports that the plugin was not loaded. This issue is fixed in 2.131.0.

CVE-2026-103012 (GCVE-0-2026-103012)

Vulnerability from cvelistv5 – Published: 2026-09-30 11:30 – Updated: 2026-09-30 14:28
VLAI
Summary
Claude Code selected an API key stored by Claude Code, for example from an earlier `/login` or written directly to its configuration, ahead of the user's valid Claude Enterprise or Team sign-in when fetching the organization's server-managed settings, even though the session itself authenticated with the Enterprise or Team account. When the settings endpoint rejected that stored key, the session started without the organization's server-managed policy (such as permission deny rules, model restrictions and managed-only locks) or, if a previously cached copy existed on the machine, kept applying that stale copy without receiving later policy changes — while continuing to operate as the organization's account. Triggering this required local access to a device with such a stored API key; the no-policy case additionally required that no managed settings had previously been cached. Endpoint-managed (MDM or file-based) settings were not affected. Claude for Enterprise organizations were affected from version 2.0.68; Claude for Work (Team) organizations from version 2.1.38, when server-managed settings became available to them. Users on standard Claude Code auto-update have received this fix already. Users performing manual updates are advised to update to version 2.1.260 or later. Thank you to Tamas Voros / NVIDIA AI Red Team for reporting this issue.

When the settings endpoint rejected that stored key, the session started without the organization\u0027s server-managed policy (such as permission deny rules, model restrictions and managed-only locks) or, if a previously cached copy existed on the machine, kept applying that stale copy without receiving later policy changes \u2014 while continuing to operate as the organization\u0027s account. Triggering this required local access to a device with such a stored API key; the no-policy case additionally required that no managed settings had previously been cached. Endpoint-managed (MDM or file-based) settings were not affected. Claude for Enterprise organizations were affected from version 2.0.68; Claude for Work (Team) organizations from version 2.1.38, when server-managed settings became available to them.\n\nUsers on standard Claude Code auto-update have received this fix already. Users performing manual updates are advised to update to version 2.1.260 or later.\n\nThank you to Tamas Voros / NVIDIA AI Red Team for reporting this issue."

Title
(D)TLS 1.2 client accepts early ChangeCipherSpec before ClientKeyExchange
Summary
A (D)TLS 1.2 client can accept a ChangeCipherSpec message before it has sent its ClientKeyExchange. No master secret has been derived at that point, so the client installs read keys derived from a known (deterministic) key and checks the server's Finished against that same key. An out-of-order ChangeCipherSpec can therefore be used by an attacker to complete the handshake in place of the server and send data the client accepts as authentic. The client's own traffic still uses correctly derived keys, so the attacker cannot read it, and the genuine server never completes the handshake. DTLS 1.2 clients are exposed because a datagram read can deliver the out-of-order records on its own. TLS 1.2 clients are exposed when the application supplies received bytes with wolfSSL_inject() or enables read ahead. For certificate suites, the attacker must be in a man-in-the-middle position. For PSK (Pre Shared Key) connections, any fake server can succeed without knowing the PSK.

CVE-2026-73535 (GCVE-0-2026-73535)

Title
Gitea second-factor bypass through OpenID identity linking
Summary
Gitea's OpenID connect handler accepts a user's password without enforcing enrolled TOTP or WebAuthn verification before completing sign-in and linking an OpenID identifier. When OpenID sign-in is enabled, an attacker who knows the victim's password can obtain a session and link an attacker-controlled identifier. The attacker can then sign in through that identifier without the victim's password or second factor, and a password change does not remove the link.
Severity
No CVSS data available.

CVE-2026-73446 (GCVE-0-2026-73446)

Vulnerability from cvelistv5 – Published: 2026-09-15 23:08 – Updated: 2026-09-16 19:34
VLAI
Title
Security Advisory 0160
Summary
On affected platforms running Arista EOS with IS-IS configured on a broadcast interface, an unauthenticated attacker can send a crafted IS-IS Hello Protocol Data Unit (PDU) that causes the device to tear down an established IS-IS adjacency. This may result in traffic disruption and loss of IP reachability for prefixes advertised through that adjacency.

Title
Russh: Channel-scoped server callbacks can be reached without an open channel
Summary
Russh is a Rust SSH client & server library. Prior to 0.62.5, russh dispatches channel-scoped Handler callbacks for recipient channel IDs that were never opened or confirmed in russh/src/server/encrypted.rs, server_read_authenticated, and the exec_request callback. Version 0.62.5 fixes the issue.

CAPEC-463: Padding Oracle Crypto Attack

An adversary is able to efficiently decrypt data without knowing the decryption key if a target system leaks data on whether or not a padding error happened while decrypting the ciphertext. A target system that leaks this type of information becomes the padding oracle and an adversary is able to make use of that oracle to efficiently decrypt data without knowing the decryption key by issuing on average 128*b calls to the padding oracle (where b is the number of bytes in the ciphertext block). In addition to performing decryption, an adversary is also able to produce valid ciphertexts (i.e., perform encryption) by using the padding oracle, all without knowing the encryption key.
