LinkAce

This is an important security release which contains updated dependencies as well as the following fixes:

• Fixed a server-side request forgery (SSRF) issue where private/internal IP addresses could still be reached during metadata fetching due to inconsistent DNS resolution between the validator and the HTTP client.
• Fixed a CSV formula injection vulnerability in the bookmark export feature that could allow malicious spreadsheet formulas embedded in a link’s title or description to execute when the exported file was opened.
• Fixed a stored XSS vulnerability where javascript: URLs could bypass URL validation during bookmark import and execute when a user clicked the imported link.
• Fixed a stored XSS vulnerability in Markdown-rendered links that could be used to trick an administrator into creating and leaking a privileged system API token.
• Fixed an information disclosure issue where HTML bookmark exports could reveal the names of private tags belonging to other users.
