DescriptionAkaunting 3.3.0 contains a stored cross-site scripting vulnerability in the XLSX item-import workflow. An authenticated Manager can import an item whose name contains HTML. When another authenticated user selects that item while creating a document, Akaunting places the stored name in an invoice or bill line item through Vue v-html, causing attacker-controlled markup to execute in the victim's Akaunting origin.

Solutions

CNA: Apply an upstream patch that treats imported item names as untrusted text in every write path, and replace the document line item's v-html rendering with a text-only Vue binding. Upgrade to the vendor-fixed release once one is published.

Workarounds

CNA: Restrict item-import permission to trusted administrators, review existing item names for markup, and avoid selecting untrusted imported items until a vendor fix is available.
