    Security Advisory – Google Chrome Browser Version 80 Updates and Ex Libris Products and Services - February 13, 2020


    Google will roll out a new version of Google Chrome (80) that will implement a secure-by-default model for cookies using the SameSite attribute, enabled by a new cookie classification system.  The SameSite attribute protects users from cross-site request forgery, where an end user may erroneously submit a web request that they did not intend.   

    The roll out will start the week of February 17, 2020.

    As of February 2020, only cookies with the SameSite set to "None" and tagged as Secure will be able to send cross-sites and will require encrypted HTTPS connection access.  Google Chrome (80) new default cookie attribute will be set to SameSite="Lax."  Previously, the SameSite cookie attribute default was set to SameSite="None."



    Affected Systems

    Alma, Primo, Leganto, campusM, RefWorks, SFX and 360 Link will be affected by the new Chrome update.

    Although the change was intended to discourage malicious cookie tracking, it also has the potential to affect Ex Libris products and services that leverage application cookies within the same web page that have a different domain than the one being used by Ex Libris.

    Custom integrations relying on non-secure (HTTP) protocols or cookies, might be impacted by the new release of Google Chrome.

    Tests and Certifications

    The mitigation for this issue has been identified, tested and certified for all Ex Libris products.
