Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Chamilo LMS before 1.11.42 and 3.0.0 contains a stored cross-site scripting vulnerability that allows unauthenticated attackers to inject malicious script payloads into survey answers by computing deterministic invitation codes and bypassing authorization checks in the survey submission endpoint. Attackers can submit crafted answers containing unescaped HTML rendered in reporting views to execute arbitrary scripts in the browser sessions of teachers or administrators, enabling persistent backdoor account creation by exploiting the victim's authenticated session.Show less

Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in IdeaSoft Software Industry and Trade Inc. Smart E-Commerce allows Reflected XSS. This issue affects Smart E-Commerce: before 8.4.2.0.Show less

Concrete CMS RSS Displayer block below version 9.5.3 rendered remote feed item titles without HTML escaping, resulting in stored cross-site scripting. An attacker able to control a title in a syndicated feed could execute script in the site origin for any visitor to the affected page, including administrators, without holding an account on that site. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 6.0 with vector CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N.

AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the Bookmark plugin where chapter names are not encoded before being concatenated into public watch-page HTML. A video owner can inject malicious scripts via the bookmark name parameter, and every visitor of that video executes the payload in the AVideo origin.Show less

AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the LoginControl plugin that fails to HTML-encode PGP public keys echoed into a textarea element. An authenticated attacker can inject malicious JavaScript by submitting a crafted public key, which executes in an administrator's session when viewing the user's profile tab.Show less

AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the CustomizeUser plugin where the field_name parameter is stored raw without sanitization. Administrators can inject malicious scripts via the add.json.php endpoint that execute when viewing extra info pages or profile forms that render the typeToHTML function.Show less

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the user 'donationLink' profile field. User::setDonationLink() (objects/user.php) stores the value and save() validates it only with filter_var(..., FILTER_VALIDATE_URL), which accepts strings such as http://evil.example/"onmouseover=alert(document.domain)//, while getDonationLink() applies only strip_tags() and does not encode double quotes. plugin/CustomizeUser/actionButton.php echoes the value unencoded into an <a href="..."> attribute, and that button is included from view/modeYoutubeBottom.php on the watch page when the CustomizeUser option allowDonationLink is enabled. An authenticated user who updates their own profile via objects/userUpdate.json.php can therefore break out of the href attribute and inject an event handler that executes JavaScript in the browser of any visitor—including an administrator—who views the attacker's videos and interacts with (for example, hovers over) the donation button. The issue was unfixed at the time of reporting.Show less

AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the YPTWallet plugin where user-supplied CryptoWallet values are base64-encoded but not HTML-escaped before storage in wallet_log.information. Administrators viewing pending withdrawal requests in pendingRequests.php execute the stored markup in their session, allowing attackers to perform administrative actions via same-origin fetch requests.Show less

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a reflected cross-site scripting vulnerability in plugin/Gallery/view/Category.php when SubCategorys is enabled. The getBackURL parameter is echoed into an href attribute without HTML encoding, allowing attackers to inject malicious scripts that execute in visitors' browsers when they interact with the Back control.Show less

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in UserGroups::setGroup_name() that fails to sanitize group_name input. Administrators with canAdminUserGroups permission can inject malicious HTML and JavaScript that executes in the browser when other administrators access the user manager interface.Show less

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a reflected cross-site scripting vulnerability in confirmLivePassword.php that copies REQUEST_URI into a form action attribute without encoding. Attackers can craft a malicious URL with a quote character to break out of the action attribute and inject event handlers that execute in the victim's browser within the site origin.Show less

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a reflected cross-site scripting vulnerability in plugin/Live/confirmLivePassword.php. The script interpolates the unauthenticated GET parameter u (which is not covered by $securityFilter) directly into an <img src="..."> attribute without URL- or HTML-encoding. A remote attacker can craft a link containing a double-quote character in u (with a non-empty key parameter and no valid c parameter) to close the src attribute and inject an additional tag with an onerror handler, executing arbitrary JavaScript in the site's origin in the browser of any user, including an administrator, who opens the link. No patched version was available at the time of the advisory.Show less

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a reflected cross-site scripting vulnerability in the showAlertMessage() function that inserts the raw Referer header into a JavaScript comment without encoding. Attackers can craft a Referer header containing */ to close the comment and inject arbitrary JavaScript that executes in the site origin for visitors arriving from the attacker-controlled page.Show less

The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘comment’ parameter in all versions up to, and including, 6.2.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.Show less

The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the bulk edit preset export/import mechanism in versions up to and including 3.35. This is due to insufficient output escaping on preset field values when they are rendered in HTML attribute contexts in the mla_generate_bulk_edit_form_fieldsets() function and mla-bulk-edit-fieldsets.tpl template. While wp_kses() filtering is applied during preset export for users without unfiltered_html capability, this does not prevent attribute injection attacks since the malicious payload consists of quotes and HTML attributes rather than HTML tags. When preset values are retrieved and rendered, they are directly assigned to template variables without esc_attr() escaping and then inserted into input element value attributes via simple string replacement. This makes it possible for authenticated attackers, with Author-level access and above (upload_files capability), to inject arbitrary web scripts that execute when an administrator imports the poisoned preset and the targeted input field receives focus.Show less

The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'mla_gallery' shortcode in versions up to and including 3.35. This is due to insufficient input sanitization and output escaping on the mla_link_href parameter when mla_output is set to 'paginate_links', where the _paginate_links() function processes the value through mla_process_shortcode_parameter() and _replace_query_parameter() without proper URL escaping, then outputs it directly in href attributes without applying esc_url(). This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.Show less
