Title
YesWiki before 4.6.7 Session Fixation via Login in AuthController.php
Summary
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.

Title
YesWiki before 4.6.7 SQL Injection via nuagetag tags parameter
Summary
YesWiki before 4.6.7 contains an SQL injection vulnerability in the Bazar nuagetag action, which concatenates the unescaped tags attribute into a raw SQL IN clause. Attackers with page-write access (unauthenticated on default installs) can embed a nuagetag tag ending in a backslash to break quote parity and inject a UNION subquery, exfiltrating password hashes and arbitrary table data.

Title
YesWiki before 4.6.7 Stored XSS via Unsanitized SVG Upload in Bazar FileField
Summary
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.
Severity
5.4 (Medium)

Title
YesWiki before 4.6.7 Unauthenticated Blind SQL Injection via newtextsearch
Summary
YesWiki before 4.6.7 contains a blind SQL injection vulnerability in the {{newtextsearch}} action because Bazar list option ids are concatenated into SQL REGEXP/LIKE clauses in actions/newtextsearch.php without escaping. Anonymous attackers can plant a malicious option id in an anonymously editable Bazar list and use search requests as a boolean oracle to read arbitrary database data, including admin password hashes from the yeswiki_users table.

Title
YesWiki before 4.6.7 SQL Injection via filtertags filterN parameter
Summary
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.

YesWiki before 4.6.7 ReDoS via wakka.php Edit-Preview Endpoint
Summary
YesWiki before 4.6.7 contains an algorithmic-complexity denial of service in the wakka.php formatter due to an O(n^2) markdown-link regex. Unauthenticated attackers can submit a small crafted body of bracket characters to the page-edit preview endpoint to pin PHP-FPM workers and saturate the pool.

Title
YesWiki before 4.6.7 ACL Bypass and Stored XSS via pointimage Action
Summary
YesWiki before 4.6.7 contains a missing authorization flaw in the pointimage action (tools/attach/actions/pointimage.php), which saves content to an attacker-chosen page with write ACL checks bypassed. Unauthenticated attackers can POST pagetag, title, and description fields to any page rendering {{pointimage}} to append raw HTML or JavaScript to any wiki page, including pages whose write ACL restricts editing, causing stored cross-site scripting in viewers' and administrators' browsers.

YesWiki before 4.6.7 Authorization Bypass via Comments API editComment
Summary
YesWiki before 4.6.7 contains an authorization bypass vulnerability in the comments API editComment route that allows authenticated low-privilege users to overwrite arbitrary pages or comments by supplying their own page as the pagetag field. Attackers can send a POST request to the api/comments endpoint targeting a victim tag, bypassing per-page write ACLs to replace content and reparent existing pages or comments.
