Microsoft Authenticator’s Unclaimed Deep Link: A Full Account Takeover Story (CVE-2026–26123)
This vulnerability is an Authentication Bypass, specifically a session hijacking issue affecting the Microsoft Authenticator app. The root cause was improper handling of deep links within the application, which allowed malicious actors to craft unclaimed deep links containing account tokens. When users clicked these links, their active sessions were hijacked, resulting in full account takeover without requiring any user interaction other than clicking a link. To exploit this, an attacker could generate a malicious deep link with an embedded account token and share it via SMS or email. The session hijack occurred due to the application's failure to verify the authenticity of deep links before processing them. This vulnerability has been assigned CVE-2026–26123. Microsoft rewarded $50,000 for this find and immediately patched the issue. To prevent similar vulnerabilities, it is crucial to thoroughly validate and sanitize all user-controlled inputs, including deep links. Key lesson: Always verify the authenticity of user-supplied data before processing it. #BugBounty #Cybersecurity #AuthenticationBypass #SessionHijacking #Infosec -
LM Challenge-Response Hash Always Sent in SMB Authentication
This vulnerability is an Authentication Bypass due to the consistent transmission of LM Challenge-Response hash during SMB authentication. The application failed to disable the LM hash in favor of the more secure NTLM hash, allowing attackers to perform offline attacks against weak LM hashes. The researcher discovered this by observing the network traffic during SMB authentication and identifying the presence of LM hashes, which should have been deprecated. The LM hash is susceptible to dictionary attacks, allowing attackers to crack passwords offline. The system's flawed configuration resulted in the consistent transmission of LM hashes, making it easier for attackers to perform offline attacks. This vulnerability could lead to account takeovers, unauthorized access, and data breaches. The researcher received $5,000 for this discovery. To prevent similar issues, it is crucial to disable the LM hash and ensure that only NTLM hashes are transmitted during SMB authentication. Key lesson: Always use stronger authentication mechanisms like NTLM over deprecated LM hashes. #BugBounty #Cybersecurity #WebSecurity #AuthenticationBypass #SMB -

Critical GitHub Enterprise Server Flaw Allows Authentication Bypass
Date: May 21, 2024
CVE: [[CVE-2024-4985]]
Vulnerability Type: Improper Authentication
CWE: [[CWE-287]]
Sources: Cyber Security News, SecurityWeek, The Hacker NewsIssue Summary
A critical vulnerability in GitHub Enterprise Server, identified as CVE-2024-4985, was discovered that allows attackers to bypass authentication. This flaw, found in versions 3.9.14, 3.10.11, 3.11.9, and 3.12.3, permits unauthorized access to repositories and sensitive data by exploiting a weakness in the SAML SSO authentication process.
Technical Key Findings
The vulnerability arises from a logic error in the SAML SSO authentication process, where the server fails to verify the validity of digital signatures on SAML responses properly. Attackers can craft SAML assertions with any certificate, which the server incorrectly accepts, allowing the spoofing of user identities, including admin accounts.
Vulnerable Products
- GitHub Enterprise Server versions 3.9.14
- GitHub Enterprise Server versions 3.10.11
- GitHub Enterprise Server versions 3.11.9
- GitHub Enterprise Server versions 3.12.3
Impact Assessment
Exploitation of this vulnerability could lead to unauthorized access to private repositories, sensitive data, and administrative controls. This can result in data breaches, code tampering, and potential intellectual property theft.
Patches or Workaround
GitHub has released patched versions (3.9.15, 3.10.12, 3.11.10, and 3.12.4) to address this issue. As an interim measure, enabling SAML certificate pinning can mitigate the risk. Additionally, auditing access logs for suspicious activity and rotating credentials is advised.

GitLab Vulnerability to GitHub-Style CDN Flaw Allowing Malware Hosting
Date: April 22, 2024
CVE: Not specifically assigned
Vulnerability Type: Authentication bypass
CWE: [[CWE-22]], [[CWE-427]]
Sources: Bleeping Computer Article, Duo Security ArticleIssue Summary
GitLab has been identified as vulnerable to a similar flaw that was found in GitHub, where the platform's "comments" feature can be abused to host malware. This vulnerability allows threat actors to upload malicious files to GitLab's CDN under the guise of legitimate projects, making them appear as if they are part of reputable repositories.
Technical Key findings
The flaw stems from the ability to generate links to uploaded files in the comment section before saving or posting the comment. These files, although potentially never visible in a public comment, receive a CDN URL that remains accessible even if the comment is deleted.
The format followed by such files uploaded to GitLab CDN is:
_https://gitlab.com/{project_group_namr}/{repo_name}/uploads/{file_id}/{file_name}_
For videos and images, the files will be stored under the/assets/path instead.Vulnerable products
The vulnerability affects all versions of GitLab that include the "comments" feature with file upload capabilities.
Impact assessment
This vulnerability can be exploited to distribute malware by disguising malicious files as legitimate project files, potentially leading to widespread security breaches if these files are executed by unsuspecting users.
Patches or workaround
As of the latest updates, specific patches for this CDN flaw have not been detailed. Users are advised to remain vigilant about files downloaded from repository-related URLs and verify their authenticity.

🚨 Mastodon Vulnerability Patched! CVE-2024-25618 🛡️
A security flaw - CVE-2024-25618 - was fixed, in Mastodon's software to prevent potential account takeovers. This vulnerability allowed attackers to bypass authentication mechanisms via a crafted request, posing a significant risk to the platform's integrity.
It enabled new logins from certain authentication providers (like CAS, SAML, OIDC) to merge with existing local accounts sharing the same email. This could lead to someone taking over your account if the provider allows changing emails or if there are multiple providers set up.
Here's how it works: When someone logs in using an external provider for the first time, Mastodon checks for an existing account with the same email. However, relying only on the email could result in hijacking your Mastodon account if the provider allows changing it. The Mastodon team swiftly deployed a patch, reinforcing the security of user accounts and the broader ecosystem. Remember, keeping software up-to-date is crucial for safeguarding against such vulnerabilities. 🔄🔐
The commit "b31af34c9716338e4a32a62cc812d1ca59e88d15" signifies this update. For further details, check out their advisory.
A big thanks to the discoverers Dominik George and Pingu from Teckids, and the Mastodon team for their rapid response in improving our digital defenses. Stay secure, everyone! ✨🐘
