CVE-2026-104451 1 Yeswiki 1 Yeswiki 2026-10-02 4.3 Medium
YesWiki before 4.6.7 contains a cross-site request forgery vulnerability in RevisionsHandler that allows attackers to restore old page revisions through GET requests lacking CSRF token validation. Attackers can lure write-capable users into a top-level navigation with the restoreRevisionId parameter, silently overwriting current page content with stale or vandalized revisions.
CVE-2026-104447 1 Yeswiki 1 Yeswiki 2026-10-02 7.1 High
YesWiki before 4.6.7 contains a cross-site request forgery vulnerability in the autoupdate UpdateAction that allows attackers to delete installed packages via unprotected GET requests. Attackers can lure a logged-in administrator to a crafted link with action=delete and a package parameter to remove extensions like bazar, breaking core site functionality.
CVE-2026-104443 1 Yeswiki 1 Yeswiki 2026-10-02 8.1 High
YesWiki before 4.6.7 contains an empty-filter scope bypass in the triples delete API that allows any authenticated user to delete or forge arbitrary semantic triples regardless of ownership. Attackers can send an empty filter to the triples delete endpoint to remove the admins-group membership triple, emptying the admin group and causing a site-wide authorization lockout.
CVE-2026-104439 1 Yeswiki 1 Yeswiki 2026-10-02 5.3 Medium
YesWiki before 4.6.7 contains a user enumeration vulnerability in LostPasswordAction.php that allows unauthenticated attackers to confirm registered email addresses through differing responses. Attackers can submit emails to the MotDePassePerdu recovery page without rate limiting to identify valid accounts for targeted phishing or password-spraying.
CVE-2026-104456 1 Yeswiki 1 Yeswiki 2026-10-02 7.6 High
YesWiki before 4.6.7 contains a second-order SQL injection vulnerability in AclService::updateRequestWithACL, where a stored username is concatenated unescaped into a read-ACL LIKE clause. Attackers can self-register an account name containing a double-quote payload, then load non-admin ACL-filtered listings to read database contents and bypass read ACLs.
CVE-2026-104466 1 Yeswiki 1 Yeswiki 2026-10-02 5.4 Medium
YesWiki before 4.6.7 contains a stored cross-site scripting vulnerability in formatters/wakka.php that allows users who can edit pages or post comments to inject event handlers by placing quotes in markdown image URLs. Attackers can store a crafted markdown image whose src breaks out of the attribute to add an onerror handler, executing JavaScript in viewers' browsers, including administrators.
CVE-2026-104452 1 Yeswiki 1 Yeswiki 2026-10-02 5.4 Medium
YesWiki before 4.6.7 contains a cross-site request forgery vulnerability in the filemanager page handler, which deletes page attachments on GET requests without validating a CSRF token. Attackers can lure a logged-in page owner or administrator into a top-level GET navigation with do=del, erase, or emptytrash, deleting or permanently purging the page's attachments.
CVE-2026-104473 1 Yeswiki 1 Yeswiki 2026-10-02 6.1 Medium
YesWiki before 4.5.3 contains multiple reflected cross-site scripting vulnerabilities that allow remote attackers to inject JavaScript through unsanitized parameters such as incomingurl, id, file, tags, and template. Attackers can lure authenticated or unauthenticated users into opening crafted links to hijack sessions and trigger authenticated requests against backend functionality.
CVE-2026-104469 1 Yeswiki 1 Yeswiki 2026-10-02 6.8 Medium
YesWiki before 4.6.7 contains a session fixation vulnerability that allows attackers to hijack authenticated sessions because login does not regenerate the PHP session ID. Attackers who set or learn a victim's pre-authentication YesWiki-* session cookie can reuse it after login to access private content and perform actions with the victim's privileges.
CVE-2026-104465 1 Yeswiki 1 Yeswiki 2026-10-02 6.1 Medium
YesWiki before 4.6.7 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject scripts via the field parameter of the mail handler. Attackers can craft links whose field value breaks out of the ajax-mail-form action attribute to execute JavaScript in victims' browsers.
CVE-2026-104461 1 Yeswiki 1 Yeswiki 2026-10-02 5.4 Medium
YesWiki before 4.6.7 contains a stored cross-site scripting vulnerability in the Bazar FileField, which validates only the upload's file extension and never calls HtmlPurifierService::cleanFile, so SVG files are stored verbatim and served inline as image/svg+xml. Authenticated users can submit entries via POST /api/entries/{formId} with SVG files containing script that executes in the wiki origin when the file is opened, enabling administrator session or account compromise.
CVE-2026-104457 1 Yeswiki 1 Yeswiki 2026-10-02 8.6 High
YesWiki before 4.6.7 contains an SQL injection vulnerability in the Bazar filtertags action, which wraps unescaped filterN attribute tokens in quotes and concatenates them into a raw tags.value IN (...) clause. Unauthenticated attackers on default installs can save filtertags markup in a page with a trailing-backslash token that breaks quote parity under MySQL backslash escaping. This lets them inject a five-column UNION subquery to read arbitrary table data such as password hashes.
CVE-2026-104453 1 Yeswiki 1 Yeswiki 2026-10-02 5.4 Medium
YesWiki before 4.6.7 contains a cross-site request forgery vulnerability in the admintag action that allows attackers to delete tag associations by luring administrators to crafted GET links. Attackers can supply a wide id range in the delete_tag parameter via top-level navigation, carrying the SameSite=Lax admin cookie, to bulk-delete tag triples.
CVE-2026-104449 1 Yeswiki 1 Yeswiki 2026-10-02 6.5 Medium
YesWiki before 4.6.7 contains an access control vulnerability allowing unauthenticated attackers to overwrite any existing wiki page, including pages whose write ACL restricts editing, via the Bazar entry-creation flow. Attackers can submit a crafted entry with an attacker-controlled id_fiche matching an existing page, overwriting its body for mass defacement and content destruction.
CVE-2026-104445 1 Yeswiki 1 Yeswiki 2026-10-02 8.2 High
YesWiki before 4.6.7 contains an authentication bypass vulnerability in the ActivityPub inbox that fails to bind the verified HTTP signature signer to the activity actor. Unauthenticated attackers with any ActivityPub keypair can send signed Delete or Update activities referencing a mirrored entry's sourceUrl to delete or overwrite other actors' federated entries.
CVE-2026-104441 1 Yeswiki 1 Yeswiki 2026-10-02 5.3 Medium
YesWiki before 4.6.7 contains an unauthenticated server-side request forgery vulnerability that allows remote attackers to make the server fetch arbitrary hosts and ports via the {{valeur}} action's url parameter. Attackers can submit the action through the content parameter of handlers/page/render.php to probe internal HTTP services and read back response content matching fiche markup.
CVE-2026-52772 1 Yeswiki 1 Yeswiki 2026-09-09 5.5 Medium
YesWiki is a wiki system written in PHP. Prior to version 4.6.6, Bazar form-field templates still apply |raw('html') to field.label / field.hint in attribute and label-body contexts, resulting stored XSS in form renders. This issue has been patched in version 4.6.6.
CVE-2026-52766 1 Yeswiki 1 Yeswiki 2026-09-09 9.1 Critical
YesWiki is a wiki system written in PHP. Prior to version 4.6.6, the {{erasespamedcomments}} wiki action (actions/EraseSpamedCommentsAction.php) accepts a suppr[] array from POST and deletes every wiki page whose tag appears in that array, with no authorization check anywhere in the action body or in the page-deletion path it invokes. Combined with YesWiki's allow-by-default action ACL model, any user who has page write access, which is the default for everyone (default_write_acl='*') on a fresh install can permanently delete arbitrary wiki pages, including the front page, admin pages, and pages owned by other users. This issue has been patched in version 4.6.6.
CVE-2026-52773 1 Yeswiki 1 Yeswiki 2026-09-08 6.1 Medium
YesWiki is a wiki system written in PHP. From version 4.1.0 to before version 4.6.6, YesWiki's archived-revision view reflects the time GET parameter into a hidden HTML input in handlers/page/show.php without escaping. Because MySQL coerces malformed DATETIME strings, an attacker can append HTML or JavaScript to a valid archived revision timestamp, still load that archived revision, and execute arbitrary JavaScript in the victim's browser. The vulnerable form is only rendered when the victim can both read and edit the target page. In restricted deployments this requires a victim with read and write access to that page. On a default doryphore 4.6.5 install, public pages such as PagePrincipale were editable anonymously during validation, so the issue can also affect unauthenticated visitors in that configuration. This issue has been patched in version 4.6.6.
CVE-2026-52771 1 Yeswiki 1 Yeswiki 2026-09-08 8.3 High
YesWiki is a wiki system written in PHP. From version 4.2.0 to before version 4.6.6, ApiController::deletePage() interpolates a page tag retrieved from the database into a DELETE FROM …_links WHERE to_tag = '$tag' query without escaping. The page tag is attacker-controlled — the POST /api/pages/{tag} API accepts arbitrary URL-encoded values, including single quotes, and stores them. A low-privilege authenticated user can therefore create a page whose tag is a SQL fragment, make the page non-orphaned via the standard {{include page="…"}} link mechanism, and then invoke the delete endpoint to execute arbitrary SQL inside the wiki database - including time-based blind data exfiltration from any table. This issue has been patched in version 4.6.6.
