CryptX versions before 0.088_001 for Perl compare AEAD authentication tags in non-constant time in the streaming decrypt_done path. The decrypt_done($tag) form compares it against the computed tag with memNE (memcmp() != 0), which short-circuits on the first differing byte, so its run time depends on the number of matching leading bytes. This affects all five AEAD modes: GCM, CCM, ChaCha20Poly1305, EAX and OCB. The one-shot *_decrypt_verify helpers are unaffected; they verify the tag inside lib

Invidious before version 2.20260626.0 contains a broken access control vulnerability that allows unauthenticated attackers to retrieve private playlist contents by accessing the RSS feed playlist endpoint without authentication. Attackers can supply a playlist ID to the feed endpoint to obtain the full playlist contents, owner email address, and associated video entries without any authentication.

A vulnerability was found in seladb PcapPlusPlus 25.05. The affected element is the function parse_by_block_type of the file light_pcapng.c of the component LightPcapNg Parser. Performing a manipulation of the argument captured_packet_length results in heap-based buffer overflow. It is possible to initiate the attack remotely. The attack's complexity is rated as high. The exploitability is described as difficult. The exploit has been made public and could be used.

A flaw has been found in AIDC-AI ComfyUI-Copilot up to 2.0.28. This issue affects some unknown processing of the file backend/controller/conversation_api.py of the component Workflow Checkpoint Restore Handler. Executing a manipulation can lead to improper control of resource identifiers. The attack may be performed from remote. A high complexity level is associated with this attack. The exploitability is assessed as difficult. The exploit has been published and may be used. The pull request to

A vulnerability was detected in 78 xiaozhi-esp32 up to 2.2.6. This vulnerability affects the function Application::GetInstance of the file main/protocols/mqtt_protocol.cc of the component MQTT Goodbye Handler. Performing a manipulation of the argument session_id results in denial of service. The attack is possible to be carried out remotely. The complexity of an attack is rather high. It is stated that the exploitability is difficult. The exploit is now public and may be used. The patch is named

A weakness has been identified in 78 xiaozhi-esp32 up to 2.2.6. Affected by this issue is the function ParseMessage of the file main/mcp_server.cc of the component MCP Response Handler. This manipulation causes improper synchronization. Remote exploitation of the attack is possible. The attack's complexity is rated as high. The exploitation is known to be difficult. The exploit has been made available to the public and could be used for attacks. The pull request to fix this issue awaits acceptan

A flaw has been found in arc53 DocsGPT up to 0.18.0. The affected element is the function encrypt_credentials of the file application/security/encryption.py of the component Credential Storage. This manipulation causes insufficient verification of data authenticity. It is possible to initiate the attack remotely. The complexity of an attack is rather high. The exploitability is described as difficult. The exploit has been published and may be used. The pull request to fix this issue awaits accep

A vulnerability was detected in skypilot-org skypilot up to 0.12.0. Impacted is the function username.encode of the file sky/users/server.py of the component User ID Handler. The manipulation results in use of weak hash. The attack may be performed from remote. This attack is characterized by high complexity. The exploitability is considered difficult. The exploit is now public and may be used. The vendor was contacted early about this disclosure.

### Summary `AbstractGenerator::$temporaryFiles` is a public array, and `removeTemporaryFiles()` — invoked from `__destruct()` and from a registered shutdown function — calls `unlink()` on every entry without verifying that the path is contained within the temporary folder. Any code holding a reference to a generator instance can push an arbitrary path into the array and have it deleted on script shutdown. This mirrors the KnpLabs/snappy issue [GHSA-87qc-37cw-84h4](https://github.com/KnpLabs/s

### Summary CRLF injection in `hackney_cookie:setcookie/3` (`src/hackney_cookie.erl`). The function validates `Name` and `Value` against CR/LF and control characters but concatenates the `domain` and `path` options verbatim into the output binary. If either option carries attacker-controlled data, a `Host` header forwarded as the cookie domain, a request URI forwarded as the cookie path, a `\r\n` in the value splits the `Set-Cookie` header and lets the attacker inject additional headers into th

The Rust Security Response Team was notified that Cargo incorrectly normalized the URLs of third-party registries using the [sparse index protocol][1]. If a hosting provider allowed multiple registries to be hosted with arbitrary names within the same domain, an attacker able to publish crates in a registry could obtain the credentials of others users of the same registry. This vulnerability is tracked as CVE-2026-5222. The severity of the vulnerability is **low**, due to the extremely niche re
