Is 🏷️Simple Price Alerts - Price alert for Amazon, Aliexpress, eBay, etc. safe?

Medium risk

Simple Price Alerts loads affiliate tracking URLs on shopping pages and fetches remote boun.me rules that control page hooks.

On matching shopping product pages, the extension can automatically load affiliate tracking URLs after it has been installed for more than 10 days, with the visited product URL included in request parameters. It also fetches seller rules from boun.me, and those remote rules can change which pages and page elements the content script hooks without an extension update.

What actually happens
You did this

You install the extension and, more than 10 days later, browse to a supported shopping site.

The extension's content script runs on every page (<all_urls>) and checks each URL against 21 seller rules, including Amazon, Cdiscount, eBay, and AliExpress.

The extension did this

The extension automatically requests an affiliate-tagged version of the page you're viewing and sends it to a third-party ad-tech network.

Depending on the seller, this happens via a background fetch() call, an off-screen iframe, or a full-page redirect through the extension's own bounce page, with no click or consent prompt shown.

Captured request
GEThttps://www.amazon.fr/dp/B0DXQ67BW4?tag=tsnet-21

200 OK. Fired automatically by the content script's fetch(product.productUrlAff, {mode:'no-cors', credentials:'include', referrerPolicy:'no-referrer'}) call when the Amazon.fr product page loaded, more than 10 days after install.

Captured request
GEThttps://www.awin1.com/cread.php?awinmid=6948&awinaffid=1154409&ued=https://www.cdiscount.com/f-1442016-eve1701125697540.html

302 redirect back to cdiscount.com with an awc= attribution parameter appended (200). The exact Cdiscount product URL visited is embedded in the ued= parameter.

What's embedded in the outgoing affiliate request
  • Product page URL you visited
    ued=https://www.cdiscount.com/f-1442016-eve1701125697540.html

    The exact page you viewed, including its product ID, is embedded in the affiliate request's URL on every matched product page.

  • Affiliate/merchant ID
    awinmid=6948&awinaffid=1154409

    An affiliate ID tied to the extension developer's account is attached so the ad network attributes any resulting purchase to them.

  • Browsing pattern
    amazon.fr, cdiscount.com, ebay.com, aliexpress.com, and 17 more

    Fires automatically on every matched page, not just on a 'buy' click, so the network can see which products you browse across 21 sites.
