fix: handle urlscan pagination and source errors safely - #136

WalkthroughAlienVault and urlscan now return typed ChangesSource handling
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR safely validates pagination data and improves source error reporting, but rate-limited responses with non-JSON bodies may still return the wrong error instead of a clear rate-limit result. The change is mergeable with explicit owner awareness and a bounded follow-up. Suggested reviewers: Poem

Fixed by rejecting fractional and non-finite cursor values and formatting the validated number without converting it to int. |

The lint check is failing before analyzing this PR because the All build jobs pass on Linux, macOS, and Windows, and CodeQL reports no new alerts. This appears to be an issue with the shared lint action rather than the changes in this PR. |
|
Ping @projectdiscovery — the lint test is failing because CI uses Go 1.24.0, while urlfinder requires Go 1.25.0. Could you please take a look? |

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Check the rate-limit status before decoding the body.
A 429 response can contain HTML, plain text, or an empty body. In that case, line 137 returns a decode error before this branch runs. Check resp.StatusCode and close the body before JSON decoding so all 429 responses report urlscan rate limited.

Description
This PR prevents urlscan from panicking when the API returns incomplete or malformed pagination sort values.
Previously, urlscan accessed the second sort value after only checking that the first one existed. It also used an unsafe type assertion for the first value, which could cause another panic if the API returned an unexpected type.
Pagination sort values are now validated before use and are only extracted when another page is available.
The PR also adds the missing
source.Errortype to error results in the AlienVault, Common Crawl, and urlscan sources. Without this type, the runner interpreted those errors as URL results and silently discarded them.Changes
