CVE-2009-0323
HighSummary
W przeglądarce internetowej W3C Amaya w wersjach 10.0 i 11.0 występują wielokrotne przepełnienia bufora na stosie, które mogą pozwolić zdalnym atakującym na wykonanie dowolnego kodu. Problemy te wynikają z niewłaściwego przetwarzania parametrów w funkcjach EndOfXmlAttributeValue oraz ProcessStartGI, a także w plikach html2thot.c i xml2thot.c.
Risk Assessment
Atakujący mogą wykorzystać te luki do zdalnego wykonania kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemów korzystających z tej przeglądarki. Może to prowadzić do utraty danych, przejęcia kontroli nad systemem lub innych nieautoryzowanych działań.
Recommendation
Zaleca się aktualizację przeglądarki W3C Amaya do najnowszej wersji, aby usunąć te podatności. Dodatkowo, warto monitorować i ograniczać dostęp do aplikacji, które mogą być narażone na ataki wykorzystujące te luki.

SPIP before 4.4.18 contains a remote code execution vulnerability in the editer_objet action where the arg parameter resolves SQL table names without enforcing an editable columns allowlist. Attackers with a valid nonce can inject attacker-controlled rows into the spip_jobs table, and by supplying arg=job/0 with crafted fonction and args values, these are later unserialized and executed when the cron job queue is drained.
- CVE-2026-72709Critical
SPIP before 4.4.18 contains a missing authorization vulnerability in the administrative action endpoints under ecrire/action/ that allows unauthenticated attackers to perform privileged actions by supplying a valid HMAC-SHA256 nonce without any server-side permission check via autoriser(). Attackers can obtain a valid nonce, compute it for any action as the anonymous user, and invoke the editer_auteur action directly over HTTP to reset the password of any user account, including the administrator.
- CVE-2026-54047Critical
Laci Synchroni is a decentralized mod and appearance sync server and plugin for Dalamud. Versions of the backend prior to 1.2.3 have an improper authentication vulnerability in the OAuth2 login flow, relying on client-side state by trusting the UID field inside the Authentications object of a user's local config.json file. By manually editing this file before logging in, a user can supply an arbitrary UID, and because the server fails to validate that the authenticated OAuth2 identity matches the requested UID, an attacker can fully impersonate any target user and perform actions on their behalf.

CWE-303: Incorrect Implementation of Authentication Algorithm vulnerability exists that could cause loss of confidentiality, integrity and availability of the PLC provided an application project with a lower application level is running on the PLC.
- CVE-2026-89010Critical
WAVLINK WN535M1 and WN535M3 routers running firmware prior to M35M1_V250922 contain an unauthenticated OS command injection vulnerability that allows remote attackers to execute arbitrary commands as root by sending crafted filenames to the sync_server daemon on TCP port 13136. The daemon interpolates attacker-controlled filename input containing shell metacharacters into a shell command string via sprintf() and passes it to system() without sanitization, enabling root-level command execution.
- CVE-2026-89009Critical
WAVLINK WN535M1 and WN535M3 routers running firmware prior to M35M1_V250922 contain an unauthenticated arbitrary file write vulnerability that allows remote attackers to overwrite any file on the device by sending a crafted payload to the sync_server daemon on TCP port 13136. The daemon, which runs as root and requires no authentication, accepts a 100-byte filename field in its protocol header without path canonicalization, allowing attackers to supply an absolute path and write arbitrary content to overwrite startup scripts or credential stores to achieve persistent system compromise.
- CVE-2026-87988Critical
An arbitrary file access vulnerability in Mistral Vibe allows an attacker to bypass workspace restrictions through commands classified as unconditionally allowed. Missing path validation for these commands enables access to files outside the active workspace without user approval.
- CVE-2026-87987Critical
An arbitrary code execution vulnerability in Mistral Vibe allows an attacker to bypass command permission checks using environment variable assignments preceding allowlisted commands. These assignments are excluded from inspection, enabling attacker-controlled environment variables to cause arbitrary code execution without user approval.
- CVE-2026-87986Critical
An arbitrary code execution vulnerability in Mistral Vibe allows an attacker to bypass command permission checks using shell constructs its parser cannot interpret. Unparsed portions are omitted from inspection, enabling embedded commands to execute on the user's system without approval.
- CVE-2026-87985Critical
An arbitrary code execution vulnerability in Mistral Vibe allows an attacker to bypass command permission checks using ANSI-C quoted arguments. These arguments are not properly inspected, enabling a crafted allowlisted command to execute arbitrary code on the user's system without approval.
Original NVD description (English source)
Multiple stack-based buffer overflows in W3C Amaya Web Browser 10.0 and 11.0 allow remote attackers to execute arbitrary code via (1) a long type parameter in an input tag, which is not properly handled by the EndOfXmlAttributeValue function; (2) an "HTML GI" in a start tag, which is not properly handled by the ProcessStartGI function; and unspecified vectors in (3) html2thot.c and (4) xml2thot.c, related to the msgBuffer variable. NOTE: these are different vectors than CVE-2008-6005.
