CVE-2025-52572
CriticalSummary
Hikka, użytkownik bota Telegram, ma podatność, która dotyczy wszystkich użytkowników we wszystkich wersjach. Istnieją dwa scenariusze: brak uwierzytelnionej sesji w interfejsie webowym, co pozwala atakującemu na zdalne wykonanie kodu (RCE), oraz uwierzytelniona sesja, gdzie użytkownicy mogą przypadkowo zezwolić atakującemu na dostęp do swoich kont Telegram.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla bezpieczeństwa użytkowników, umożliwiając atakującym zdalne wykonanie kodu oraz dostęp do kont Telegram ofiar. Scenariusz z uwierzytelnioną sesją został już wykorzystany w praktyce.
Recommendation
Zaleca się używanie flagi `--no-web` i nie uruchamianie bota użytkownika bez niej. Po autoryzacji w interfejsie webowym, należy zamknąć port na serwerze oraz unikać klikania 'Zezwól' w pomocniczym bocie, chyba że jest to wyraźnie wymagane.

Cross-site Scripting (XSS) vulnerability in Apache Juneau. HTML document serialization does not HTML-encode variable substitutions in page chrome fields (header, nav, footer, etc.), so applications that place request-derived values there reflect them unencoded.
- CVE-2026-73117Critical
HTTP Response Splitting (CRLF injection in HTTP headers) vulnerability in Apache Juneau. The REST server passed response header values and redirect targets to the servlet container unchecked, so request-derived data could allow header injection or redirect to an arbitrary site.
- CVE-2026-73116Critical
Insufficiently Protected Credentials vulnerability in Apache Juneau. The RestClient followed HTTP redirects while keeping credential headers from the original request, so a server redirecting to a different host, port, or from HTTPS to HTTP could receive Authorization, Cookie, Proxy-Authorization and X-API-Key headers.
- CVE-2026-73101Critical
Generation of Error Message Containing Sensitive Information vulnerability in Apache Juneau. The REST server sends the internal exception class and message to clients in a "Thrown" response header on every error response and may include internal exception messages in the error body, even with stack-trace rendering disabled.
- CVE-2026-73100Critical
Insertion of Sensitive Information into Log File vulnerability in Apache Juneau. The default REST server call logger records request headers for requests ending in a server error without redaction, so Authorization, Cookie, Proxy-Authorization and X-API-Key headers are written in cleartext to the application log.
- CVE-2026-73099Critical
Cross-Site Request Forgery (CSRF) vulnerability in Apache Juneau. The REST server accepts a "content" query parameter that replaces the request body and is enabled by default on every HTTP method including GET, so a cross-site link can deliver an attacker-chosen request body without a CORS preflight.
- CVE-2026-73098Critical
Improper control of dynamically-loaded code vulnerability in Apache Juneau. When parsing a value into a property of type java.lang.Class, the default class swap loaded the named class with initialization enabled, so input naming a class on the application classpath ran that class's static initializer.
- CVE-2026-121489Critical
Path Traversal vulnerability in Apache Juneau. The microservice DirectoryResource does not keep request paths inside its configured root directory; when an application enables the resource's view, upload or delete settings (all off by default), a client can read, write or delete files outside the root.
- CVE-2026-100109Critical
The Security For WooCommerce WordPress plugin from 1.0.10 to 1.0.16 does not perform capability checks when creating users through an action available to unauthenticated visitors, and lets the caller choose the new account's role. This allows unauthenticated attackers to create administrator accounts and take over the site.
- CVE-2026-123025Critical
An OS command injection vulnerability was discovered in the Google Cloud DNS validation module of the OPNsense os-acme-client plugin through 4.17. The DnsGcloud::prepare() method decodes the dns_gcloud_key model field and directly interpolates the gcloud_account and gcloud_project string fields into a shell command passed to proc_open() via LeUtils::run_shell_command() without validation or escaping. A remote authenticated user with privileges to issue or renew certificates through the WebGUI/API can achieve arbitrary code execution as root.
Original NVD description (English source)
Hikka, a Telegram userbot, has vulnerability affects all users on all versions of Hikka. Two scenarios are possible. 1. Web interface does not have an authenticated session: attacker can use his own Telegram account to gain RCE to the server by authorizing in the dangling web interface. 2. Web interface does have an authenticated session: due to insufficient warning in the authentication message, users were tempted to click "Allow" in the "Allow web application ops" menu. This gave an attacker access not only to remote code execution, but also to Telegram accounts of owners. Scenario number 2 is known to have been exploited in the wild. No known patches are available, but some workarounds are available. Use `--no-web` flag and do not start userbot without it; after authorizing in the web interface, close the port on the server and/or start the userbot with `--no-web` flag; and do not click "Allow" in your helper bot unless it is your explicit action that needs to be allowed.
