"According to the versions of the python-sqlalchemy packages installed, the EulerOS installation on the remote host is
affected by the following vulnerabilities :

    Underscore.js is a utility-belt library for JavaScript. Prior to 1.13.8, the _.flatten and _.isEqual
    functions use recursion without a depth limit. Under very specific conditions, detailed below, an attacker
    could exploit this in a Denial of Service (DoS) attack by triggering a stack overflow. Untrusted input
    must be used to create a recursive datastructure, for example using JSON.parse, with no enforced depth
    limit. The datastructure thus created must be passed to _.flatten or _.isEqual. In the case of _.flatten,
    the vulnerability can only be exploited if it is possible for a remote client to prepare a datastructure
    that consists of arrays at all levels AND if no finite depth limit is passed as the second argument to
    _.flatten. In the case of _.isEqual, the vulnerability can only be exploited if there exists a code path
    in which two distinct datastructures that were submitted by the same remote client are compared using
    _.isEqual. For example, if a client submits data that are stored in a database, and the same client can
    later submit another datastructure that is then compared to the data that were saved in the database
    previously, OR if a client submits a single request, but its data are parsed twice, creating two non-
    identical but equivalent datastructures that are then compared. Exceptions originating from the call to
    _.flatten or _.isEqual, as a result of a stack overflow, are not being caught. This vulnerability is fixed
    in 1.13.8.(CVE-2026-27601)

Tenable has extracted the preceding description block directly from the EulerOS python-sqlalchemy security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
