Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

File path links with line numbers are broken in v1.7.54

VERSIONS:

  • v1.6.46: :white_check_mark: WORKS - File links with line numbers are clickable and navigate correctly
  • v1.7.54: :cross_mark: BROKEN - File links with line numbers render but are non-functional

WHAT WORKS IN BOTH VERSIONS:
:white_check_mark: File links WITHOUT line numbers (e.g., file:///C:\path\to\file.py) - Opens file correctly

WHAT’S BROKEN IN v1.7.54:
:cross_mark: File links WITH line numbers (e.g., file:///C:\path\to\file.py#L42) - Link appears clickable but nothing happens when clicked

Steps to Reproduce

  1. In Cursor v1.7.54 chat, create or request a markdown link with a line number:
    [Test link](file:///C:\Users\Username\Documents\Development\pythonProjects\ocr_eval\evaluate_ocr.py#L42)
  2. Observe the link renders properly with styling
  3. Click the rendered link
  4. BUG: Nothing happens - file doesn’t open, no navigation to line 42
  5. Compare with v1.6.46: Same link works perfectly

Note:
For Step 1 above I have this test user rule :

When a user types "test link", generate a markdown link to test cursor AI file path campatibility.

### Response format:
** Raw markdown syntax **
[Test file link]
(file:///C:\Users\UserName\Documents\Development\pythonProjects\ocr_eva\evaluate_ocr.py)

## Rendered link **
[Test File link]
(file:///C:\Users\UserName\Documents\Development\pythonProjects\ocr_eva\evaluate_ocr.py#L42)

When the links are rendered as per this rule, the the first link works, but the second link doesn’t work in v1.7.54

Expected Behavior

Links with line numbers would open the file and scroll to that line number.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the detailed report. This is a clear regression in v1.7.54.

I’ll pass this to the team because:

  • Line-numbered links worked in v1.6.46 but broke in v1.7.54
  • The issue affects 400 users in your organization
  • You shared excellent repro steps and a video as evidence

Temporary workaround: if possible, roll back to v1.6.46 until we fix the issue.
