CyberRota Analysis
AI-GeneratedShlink versions 5.0.0 to 5.1.5 are vulnerable to a CSV formula injection that enables unauthenticated remote attackers to inject malicious spreadsheet formulas into exported visit data through manipulated headers. This vulnerability can lead to the execution of arbitrary code on an administrator's machine when the CSV file is opened, posing a risk to data integrity and security. Organizations using affected versions should prioritize patching to mitigate potential exploitation.

Original NVD Description
Shlink versions 5.0.0 through 5.1.5 contain a CSV formula injection vulnerability that allows unauthenticated remote attackers to plant spreadsheet formulas into exported visit data by supplying malicious values in User-Agent, Referer, or request path headers beginning with formula-triggering characters such as =, +, -, or @. Attackers can craft a single unauthenticated request against any short URL to embed DDE or WEBSERVICE formula payloads into CSV cells, which are then executed on an administrator's client machine when the exported CSV file is opened in a spreadsheet application that evaluates formulas.
