### Summary While rebuilding [PMD Designer](https://github.com/pmd/pmd-designer) for Reproducible Builds and digging into issues, I found out that passphrase for `gpg.keyname=0xD0BF1D737C9A1C22` is included in jar published to Maven Central. ### Details See https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/content/net/sourceforge/pmd/pmd-designer/README.md I removed 2 lines from https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/content/net/sourceforge/pmd/pmd-designer/pmd-designer-7.0.0.diffoscope but real content is: ``` ├── net/sourceforge/pmd/util/fxdesigner/designer.properties │ @@ -1,14 +1,12 @@ │ #Properties │ checkstyle.plugin.version=3.3.1 │ checkstyle.version=10.14.0 │ -gpg.keyname=0xD0BF1D737C9A1C22 │ -gpg.passphrase=evicx0nuPfvSVhVyeXpw │ jar.plugin.version=3.3.0 │ -java.version=11.0.22 │ +java.version=11.0.25 │ javadoc.plugin.version=3.6.3 │ jflex-output=/home/runner/work/pmd-designer/pmd-designer/target/generated-sources/jflex...

### 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...

### Summary _Short summary of the problem. Make the impact and severity as clear as possible. For example: An unsafe deserialization vulnerability allows any unauthenticated user to execute arbitrary code on the server._ There is a potential XXE(XML External Entity Injection) vulnerability when http4k handling malicious XML contents within requests, which might allow attackers to read local sensitive information on server, trigger Server-side Request Forgery and even execute code under some circumstances. ### Details _Give all details on the vulnerability. Pointing to the incriminated source code is very helpful for the maintainer._ https://github.com/http4k/http4k/blob/25696dff2d90206cc1da42f42a1a8dbcdbcdf18c/core/format/xml/src/main/kotlin/org/http4k/format/Xml.kt#L42-L46 XML contents is parsed with DocumentBuilder without security settings on or external entity enabled ### PoC _Complete instructions, including specific configuration details, to reproduce the vulnerability._ #### ...

### Summary Reposilite v3.5.10 is affected by an Arbitrary File Read vulnerability via path traversal while serving expanded javadoc files. ### Details The problem lies in the way how the expanded javadoc files are served. The `GET /javadoc/{repository}/<gav>/raw/<resource>` route uses the `<resource>` path parameter to find the file in the `javadocUnpackPath` directory and returns it's content to the user. [JavadocFacade.kt#L77](https://github.com/dzikoysk/reposilite/blob/68b73f19dc9811ccf10936430cf17f7b0e622bd6/reposilite-backend/src/main/kotlin/com/reposilite/javadocs/JavadocFacade.kt#L77): ```kotlin fun findRawJavadocResource(request: JavadocRawRequest): Result<JavadocRawResponse, ErrorResponse> = with (request) { mavenFacade.canAccessResource(accessToken, repository, gav) .flatMap { javadocContainerService.loadContainer(accessToken, repository, gav) } .filter({ Files.exists(it.javadocUnpackPath.resolve(resource.toString())) }, { notFound("Resourc...

Hi there! Here’s your quick update on the latest in cybersecurity. Hackers are using new tricks to break into systems we thought were secure—like finding hidden doors in locked houses. But the good news? Security experts are fighting back with smarter tools to keep data safe. Some big companies were hit with attacks, while others fixed their vulnerabilities just in time. It's a constant battle.

Google has revealed that its transition to memory-safe languages such as Rust as part of its secure-by-design approach has led to the percentage of memory-safe vulnerabilities discovered in Android dropping from 76% to 24% over a period of six years. The tech giant said focusing on Safe Coding for new features not only reduces the overall security risk of a codebase, but also makes the switch

### Summary When parsing unknown fields in the Protobuf Java Lite and Full library, a maliciously crafted message can cause a StackOverflow error and lead to a program crash. Reporter: Alexis Challande, Trail of Bits Ecosystem Security Team <[email protected]> Affected versions: This issue affects all versions of both the Java full and lite Protobuf runtimes, as well as Protobuf for Kotlin and JRuby, which themselves use the Java Protobuf runtime. ### Severity [CVE-2024-7254](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-7254) **High** CVSS4.0 Score 8.7 (NOTE: there may be a delay in publication) This is a potential Denial of Service. Parsing nested groups as unknown fields with DiscardUnknownFieldsParser or Java Protobuf Lite parser, or against Protobuf map fields, creates unbounded recursions that can be abused by an attacker. ### Proof of Concept For reproduction details, please refer to the unit tests (Protobuf Java [LiteTest](https://github.com/protocolbuffer...
