CVE-2009-1690
HighSummary
Podatność typu use-after-free w WebKit, używanym w Apple Safari przed wersją 4.0 oraz w różnych wersjach iPhone OS i Google Chrome, umożliwia zdalnym atakującym wykonanie dowolnego kodu lub spowodowanie awarii aplikacji poprzez ustawienie nieokreślonej właściwości tagu HTML. Problem ten jest związany z rekurencją w niektórych obsługiwanych zdarzeniach DOM.
Risk Assessment
Atakujący może wykorzystać tę podatność do zdalnego wykonania kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemów oraz danych użytkowników. Może to również prowadzić do awarii aplikacji, co wpływa na dostępność usług.
Recommendation
Zaleca się aktualizację przeglądarek i systemów operacyjnych do najnowszych wersji, które zawierają poprawki bezpieczeństwa eliminujące tę podatność. Należy również monitorować i ograniczać dostęp do aplikacji, które mogą być narażone na ataki wykorzystujące tę lukę.

GitLab EE versions from 18.3 before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2 contain a vulnerability that, under certain conditions, allows an authenticated user with Duo Chat access to obtain Advanced Search instance configurations and sensitive credentials. Exploitation uses a specially crafted GraphQL subscription argument to bypass serialization and perform server object lookup.

GitLab CE/EE versions from 18.7 before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2 contain a vulnerability in the repository commits API caused by improper path confinement and missing authentication enforcement. Under certain conditions, an unauthenticated user could read arbitrary files from the GitLab server.
- CVE-2026-90456Critical
An example environment-configuration file for a bundled inventory-management component ships with a fixed, publicly-known administrative password. A deployment that copies this example file into active configuration without running the setup routine that regenerates credentials will expose that component's administrative interface to anyone aware of the default value.
- CVE-2026-53952Critical
GetSimple CMS (v3.4.0a and below) and GetSimple CMS CE (v3.3.22 and below) contain a logic flaw allowing unauthenticated attackers to create a new administrator account. The automated control that deletes admin/setup.php after installation is neutralized by a self-exclusion bug, leaving the setup script accessible. As of publication, no patched versions are available.

The WS-Security (wsse:UsernameToken) verification routine in the Sofia IPC daemon in Xiongmai IP Camera XM530 firmware HMT.CM2005-v220608.1837 and earlier has an improper authentication vulnerability. A remote attacker can bypass authentication and execute privileged ONVIF actions (PTZ control, stream URL retrieval, system reboot) via a crafted SOAP request supplying the admin username with any arbitrary password when the account's stored password is empty.

In Authorizer prior to version 2.2.1, the /authorize endpoint accepts any redirect_uri without validating it against AllowedOrigins. With response_type=token or response_type=id_token, the server appends access_token, id_token, and refresh_token as query parameters and issues a 302 redirect to the attacker-supplied URL. An unauthenticated attacker can obtain the client_id from the public /graphql endpoint.
- CVE-2026-82617Critical
The built-in name-finder patterns EMAIL and URL in Apache OpenNLP contain ambiguous nested quantifiers, enabling a ReDoS attack. A crafted input can trigger super-linear backtracking or unbounded matcher recursion, leading to CPU exhaustion or StackOverflowError. The issue affects versions 2.0.0 through 2.5.11 and 3.0.0-M1 through 3.0.0-M5.
- CVE-2026-72710Critical
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.
Original NVD description (English source)
Use-after-free vulnerability in WebKit, as used in Apple Safari before 4.0, iPhone OS 1.0 through 2.2.1, iPhone OS for iPod touch 1.1 through 2.2.1, Google Chrome 1.0.154.53, and possibly other products, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) by setting an unspecified property of an HTML tag that causes child elements to be freed and later accessed when an HTML error occurs, related to "recursion in certain DOM event handlers."
