CVE-2010-1585
HighSummary
Metoda nsIScriptableUnescapeHTML.parseFragment w mechanizmie ochrony ParanoidFragmentSink w Mozilla Firefox przed wersją 3.5.17 oraz 3.6.x przed 3.6.14, Thunderbird przed 3.1.8 i SeaMonkey przed 2.0.12 nie sanitizuje poprawnie HTML w dokumencie chrome. Umożliwia to zdalnym atakującym wykonanie dowolnego JavaScriptu z uprawnieniami chrome za pomocą URI javascript: wprowadzonym do rozszerzenia.
Risk Assessment
Podatność ta stwarza ryzyko wykonania złośliwego kodu JavaScript przez atakujących, co może prowadzić do przejęcia kontroli nad aplikacją lub kradzieży danych użytkowników. Organizacje powinny być świadome potencjalnych zagrożeń związanych z używaniem nieaktualnych wersji przeglądarek.
Recommendation
Zaleca się aktualizację Mozilla Firefox, Thunderbird i SeaMonkey do najnowszych wersji, aby usunąć tę podatność. Dodatkowo, warto przeprowadzić audyt używanych rozszerzeń w celu zminimalizowania ryzyka.

The CryptoPayment Gateway WordPress plugin from 1.2.1 to 1.2.2 does not apply an authorization check on one of its AJAX endpoints, allowing unauthenticated users to invoke administrative operations, including deleting arbitrary files on the server, overwriting the payment gateway configuration and recovering stored wallet credentials in cleartext.
- CVE-2026-90558Critical
sngrep through 1.8.4 contains stack buffer overflow vulnerabilities in SIP attribute formatting routines when header values exceed the 255-byte buffer limit. Attackers can craft malicious SIP packets with oversized Call-ID, X-Call-ID, or other header fields to overflow stack buffers and cause crashes or execute arbitrary code during packet parsing and rendering.
- CVE-2026-78159Critical
The Events Calendar plugin for WordPress in all versions up to and including 6.17.3 is vulnerable to Remote Code Execution via the parse_array function. Insufficient validation of the widget 'classes' map allows a plain-array payload to bypass the is_safe_widget_instance() object check and reach the callable-invocation sink in Element_Classes::parse_array(). This enables unauthenticated attackers to execute code on the server, provided comments are enabled on tribe_events posts and at least one comment containing a crafted wp:legacy-widget block has been submitted.
- CVE-2026-78006Critical
The Events Calendar plugin for WordPress in all versions up to and including 6.17.4 is vulnerable to Remote Code Execution via the is_safe_widget_instance function. Insufficient protection in is_safe_widget_instance can be bypassed because PHP fires magic methods during its pre-parse, combined with enable_rendering_widget_copied() forging a valid wp_hash integrity attribute before unserialize() is reached. This enables unauthenticated attackers to execute code on the server, as the plugin's V2 single-event template runs do_blocks() over buffered comment HTML and WordPress returns a moderation-hash URL allowing an unauthenticated commenter to immediately view their own pending comment.
- CVE-2026-85681Critical
The WP Component WordPress plugin through 2.2.4 does not have any capability or nonce checks on one of the actions it makes available to unauthenticated users, and it takes both the option name and the option value from the request, allowing unauthenticated attackers to overwrite any of the site's options. On a single site installation this leads to a full takeover, as registration can be enabled with a default role of administrator.
- CVE-2026-84171Critical
The WP images upload on piclect WordPress plugin through 1.0 does not validate the name or type of uploaded files before writing them to a publicly accessible directory, allowing unauthenticated attackers to upload arbitrary files and execute arbitrary code on the server.
- CVE-2026-82845Critical
The Masteriyo LMS WordPress plugin before 3.4.1 does not prevent user-supplied values held as metadata from being deserialized when they are read back, allowing users with a minimal account to inject arbitrary PHP objects and, by way of a class shipped in a library bundled with the plugin, write and execute arbitrary code on the server. A weaker form of the same issue is reachable without an account and yields an arbitrary file write rather than code execution.
- CVE-2026-81402Critical
The DS Ad Rotator WordPress plugin through 0.8 does not perform any capability check, nonce verification, or file-type validation on its image upload handler, allowing unauthenticated attackers to upload arbitrary files, including PHP, to a web-accessible directory, which can lead to remote code execution.
- CVE-2026-77006Critical
The WebTotem Backups WordPress plugin through 1.0.1 does not validate a user-supplied file path, does not check the capability of the user making the request, and discards the result of its own CSRF check, allowing any authenticated user, such as a subscriber, to delete arbitrary files on the server, which can lead to a site takeover.
- CVE-2026-77005Critical
The CODE MONKEYS PROPOSALS WordPress plugin through 1.0.1 does not validate a user-supplied file path before deleting a file, and does not check the capability of the user making the request, allowing any authenticated user, such as a subscriber, to delete arbitrary files on the server, which can lead to a site takeover.
Original NVD description (English source)
The nsIScriptableUnescapeHTML.parseFragment method in the ParanoidFragmentSink protection mechanism in Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, Thunderbird before 3.1.8, and SeaMonkey before 2.0.12 does not properly sanitize HTML in a chrome document, which makes it easier for remote attackers to execute arbitrary JavaScript with chrome privileges via a javascript: URI in input to an extension, as demonstrated by a javascript:alert sequence in (1) the HREF attribute of an A element or (2) the ACTION attribute of a FORM element.
