The number of CISOs who report directly to the CEO is up sharply in recent years, but many still say it's not enough to secure adequate resources.

### Impact In CI contexts, the IG Publisher CLI uses git commands to determine the URL of the originating repo. If the repo was cloned, or otherwise set to use a repo that uses a username and credential based URL, the entire URL will be included in the built Implementation Guide, exposing username and credential. This does not impact users that clone public repos without credentials, such as those using the auto-ig-build continuous integration infrastructure. ### Patches This problem has been patched in release [1.8.9](https://github.com/HL7/fhir-ig-publisher/releases/tag/1.8.9) ### Workarounds Users should update to 1.8.9 or the latest release OR Users should ensure the IG repo they are publishing does not have username or credentials included in the `origin` URL. Running the command `git remote origin url` should return a URL that contains no username, password, or token. OR Users should run the IG Publisher CLI with the `-repo` parameter and specify a URL that contains no us...

The MITRE framework's applied exercise provides defenders with critical feedback about how to detect and defend against common, but sophisticated, attacks.

### Summary If an attacker can control the input to the `asteval` library, they can bypass asteval's restrictions and execute arbitrary Python code in the context of the application using the library. ### Details The vulnerability is rooted in how `asteval` performs handling of `FormattedValue` AST nodes. In particular, the [`on_formattedvalue`](https://github.com/lmfit/asteval/blob/cfb57f0beebe0dc0520a1fbabc35e66060c7ea71/asteval/asteval.py#L507) value uses the [dangerous format method of the str class](https://lucumr.pocoo.org/2016/12/29/careful-with-str-format/), as shown in the vulnerable code snippet below: ```py def on_formattedvalue(self, node): # ('value', 'conversion', 'format_spec') "formatting used in f-strings" val = self.run(node.value) fstring_converters = {115: str, 114: repr, 97: ascii} if node.conversion in fstring_converters: val = fstring_converters[node.conversion](val) fmt = '{__fstring__}' if node.f...

### Impact summary In some circumstances, debug artifacts uploaded by the CodeQL Action after a failed code scanning workflow run may contain the environment variables from the workflow run, including any secrets that were exposed as environment variables to the workflow. Users with read access to the repository would be able to access this artifact, containing any secrets from the environment. For some affected workflow runs, the exposed environment variables in the debug artifacts included a valid `GITHUB_TOKEN` for the workflow run, which has access to the repository in which the workflow ran, and all the permissions specified in the workflow or job. The `GITHUB_TOKEN` is valid until the job completes or 24 hours has elapsed, whichever comes first. Environment variables are exposed only from workflow runs that satisfy all of the following conditions: - Code scanning workflow configured to scan the Java/Kotlin languages. - Running in a repository containing Kotlin source code. - R...

### Impact XSLT transforms performed by various components are vulnerable to XML external entity injections. A processed XML file with a malicious DTD tag ( ]> could produce XML containing data from the host system. This impacts use cases where org.hl7.fhir.publisher is being used to within a host where external clients can submit XML. A previous release provided an incomplete solution revealed by new testing. ### Patches This issue has been patched as of version 1.7.4 ### Workarounds None ### References [Previous Advisory for Incomplete solution](https://github.com/HL7/fhir-ig-publisher/security/advisories/GHSA-59rq-22fm-x8q5) [MITRE CWE](https://cwe.mitre.org/data/definitions/611.html) [OWASP XML External Entity Prevention Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/XML_External_Entity_Prevention_Cheat_Sheet.html#transformerfactory)
