Authentication Bypass
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
How It Works
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications. Instead of cracking passwords through brute force, attackers manipulate the authentication process itself to gain unauthorized entry. This typically occurs through one of several pathways: exploiting hardcoded credentials embedded in source code or configuration files, manipulating parameters in authentication requests to skip verification steps, or leveraging broken session management that fails to properly validate user identity.
The attack flow often begins with reconnaissance to identify authentication endpoints and their underlying logic. Attackers may probe for default administrative credentials that were never changed, test whether certain URL paths bypass login requirements entirely, or intercept and modify authentication tokens to escalate privileges. In multi-step authentication processes, flaws in state management can allow attackers to complete only partial verification steps while still gaining full access.
More sophisticated variants exploit single sign-on (SSO) or OAuth implementations where misconfigurations in trust relationships allow attackers to forge authentication assertions. Parameter tampering—such as changing a "role=user" field to "role=admin" in a request—can trick poorly designed systems into granting elevated access without proper verification.
Impact
- Complete account takeover — attackers gain full control of user accounts, including administrative accounts, without knowing legitimate credentials
- Unauthorized data access — ability to view, modify, or exfiltrate sensitive information including customer data, financial records, and intellectual property
- System-wide compromise — admin-level access enables installation of backdoors, modification of security controls, and complete infrastructure takeover
- Lateral movement — bypassed authentication provides a foothold for moving deeper into networks and accessing additional systems
- Compliance violations — unauthorized access triggers breach notification requirements and regulatory penalties
Real-World Examples
CrushFTP suffered a critical authentication bypass allowing attackers to access file-sharing functionality without any credentials. The vulnerability enabled direct server-side template injection, leading to remote code execution on affected systems. Attackers actively exploited this in the wild to establish persistent access to enterprise file servers.
Palo Alto's Expedition migration tool contained a flaw permitting attackers to reset administrative credentials without authentication. This allowed complete takeover of the migration environment, potentially exposing network configurations and security policies being transferred between systems.
SolarWinds Web Help Desk (CVE-2024-28987) shipped with hardcoded internal credentials that could not be changed through normal administrative functions. Attackers discovering these credentials gained full administrative access to helpdesk systems containing sensitive organizational information and user data.
Mitigation
- Implement multi-factor authentication (MFA) — requires attackers to compromise additional verification factors beyond bypassed primary authentication
- Eliminate hardcoded credentials — use secure credential management systems and rotate all default credentials during deployment
- Enforce authentication on all endpoints — verify every request requires valid authentication; no "hidden" administrative paths should exist
- Implement proper session management — use cryptographically secure session tokens, validate on server-side, enforce timeout policies
- Apply principle of least privilege — limit damage by ensuring even authenticated users only access necessary resources
- Regular security testing — conduct penetration testing specifically targeting authentication logic and flows

Keycloak's Admin REST API allows authenticated administrators with delegated privileges over a realm to read or modify sensitive client configurations in the master realm by abusing a per-request in-memory cache that resolves clients by unique identifier without verifying realm ownership. The flaw affects Red Hat Build of Keycloak and Red Hat Single Sign-On 7, requires the attacker to hold privileged delegated administration rights and to know or reference a target client's unique ID, and is assessed as a moderate-priority authorization issue rather than a high-CVSS critical defect. No public exploit code was identified at time of analysis, and successful exploitation could expose client credentials or redirect administrative login attempts to malicious sites.
Missing authorization checks in the Keycloak Authorization Services policy evaluation endpoint allow an authenticated delegated administrator with limited viewing privileges to read the full profile and role information of any user in the realm, including email addresses and assigned security roles. This moderate-severity information-disclosure issue affects Red Hat Build of Keycloak and Red Hat Single Sign-On 7. No public exploit code has been identified at time of analysis.
Authentication bypass in the Tencent BrowserSkill local WebSocket daemon (bsk-cli, through v0.3.0) allows any installed browser extension that presents a syntactically valid 32-character Chrome extension ID to register as a client and intercept or manipulate the page content, DOM, and screenshots returned to the AI agent. The root cause is a missing origin allowlist (CWE-346) rather than a memory-safety bug, so exploitation is limited to hosts where a hostile extension can be loaded into the browser and the daemon is running - reflected in the assessed CVSS:3.1 vector AV:L/AC:L/PR:L/UI:N with high integrity impact (I:H) and low confidentiality/availability impact, and in the supplied CVSS 4.0 score of 6.9. No public exploit code was identified at time of analysis, the issue is not listed in CISA KEV, and the overall risk is best characterized as a moderate, locally-scoped integrity risk rather than a widespread emergency.
Hard-coded default superuser credentials in aiyiyi121 SxDevOps 1.0/1.1 let unauthenticated remote attackers log in to the management/API interface as a superuser, because the shipped password (Admin@123456, published in the project's own README) is generated by ensure_default_superuser in rbac/services.py and is never forced to be changed. The CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:N, VC/VI/VA:L) confirms no authentication or user interaction is required and that the attack is network-reachable; our own assessment rates the true impact higher (C/I/A:H) since a superuser session yields full control of managed hosts and tasks, limited only by whether the operator changed the default after initialization. The vendor has published a fix commit and states a corrected version was released; no public exploit code was identified at time of analysis, but exploitation requires no tooling beyond the documented credential, and there is no CISA KEV listing for this issue. EPSS data was not provided.
SxDevOps 1.0 and 1.1 seed demo and administrator accounts with a hard-coded default password ('Admin@123456') that is also documented in the project README, letting an unauthenticated remote attacker who can reach the login interface sign in with full administrative privileges. The flaw is only exploitable on deployments that were initialized with the demo accounts and where the password was never rotated or the accounts disabled before exposing the service; instances that set SXDEVOPS_DEMO_PASSWORD/SXDEVOPS_ADMIN_INITIAL_PASSWORD or applied the vendor fix are not affected. No public exploit code was identified at time of analysis, and the vendor has published a fixing commit (2b4bf8585c3e731e7a8af30801ea46680bc783f9).
Unauthenticated attackers can tamper with arbitrary bookings on any internet-reachable WordPress site running the Tripzzy plugin in versions 1.3.4 through 1.5.0, because its administrative booking-management actions perform no capability or ownership checks and are gated only by a token the plugin hands to any anonymous visitor on request. Exploitation allows alteration of booking contents, stored totals, and notes (integrity impact only; no confidentiality or availability impact was assessed), and publicly available exploit code exists - the WPScan entry is tagged as an exploit reference. No special configuration is required, no credentials or user interaction are needed, and there is no indication of confirmed active exploitation in CISA KEV at the time of analysis; EPSS data was not provided.
The certificate validation route in Nginx Proxy Manager through 2.15.1 (internalCertificate.validate in backend/internal/certificate.js) is reachable without authentication, letting any remote caller submit arbitrary certificate material to the backend. Publicly available exploit code exists, but the project has not responded to the early issue report, so no fixed release is confirmed; the practical impact is constrained because the endpoint parses and echoes back only the certificate the caller supplied rather than returning stored data, leaving malformed-input handling in the OpenSSL parsing path as the main residual concern. As our independent assessment notes, this is a moderate-priority issue and the raw 6.9 CVSS 4.0 score somewhat overstates the real-world risk.
Unauthenticated username enumeration in Dromara UJCMS through version 12.3.1 allows remote attackers to query the UserController username-existence endpoint and determine whether a given account name is registered on the target site, leaking account information without any credentials, user interaction, or special configuration. The independent assessment rates this as a low-impact confidentiality leak (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N), whose practical value lies in feeding follow-on password-guessing or credential-stuffing campaigns against confirmed accounts rather than in direct compromise. No public exploit code has been identified at time of analysis and the vulnerability is not confirmed as actively exploited (no CISA KEV listing); the vendor was notified via a GitHub issue but has not responded, so no fixed release is available.
Missing OAuth token validation in Pixelfed up to 0.12.11 allows an authenticated user without a valid OAuth token to reach the /api/v1 instancePeers endpoint and enumerate federated peer instances, a low-sensitivity information exposure tracked as CWE-306. Publicly available exploit code exists, and the vendor has released a patch (v0.12.10, commit 68dca5097305fa0065d029587b2233524636025a) with a GitHub issue and PR. The independent assessment treats this as low priority: the CVSS vector requires PR:L (authenticated) access, the exposed peer list is often publicly available anyway, and there is no user-data confidentiality, integrity-write, or availability impact beyond peer enumeration.
Keycloak's OpenID Connect token refresh path can issue fresh access tokens on behalf of an OIDC client that an administrator has already disabled, because the server restores requested audiences from stored client IDs without re-checking whether that audience client is still enabled. An attacker who already possesses a valid, unexpired refresh token for the affected client can therefore keep obtaining usable access tokens after the client is turned off, but only against resource servers that validate the JWT locally (offline signature/claim checks) rather than calling Keycloak for introspection or userinfo. Scoring is low at CVSS 4.2 (AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N), no public exploit code was identified at time of analysis, and exploitation requires both a live refresh token and a client that was disabled after that token was issued.
Authentication bypass in the OpenPanel tracking API allows unauthenticated remote attackers to inject forged revenue metrics and evade bot-detection filters by supplying arbitrary dummy secrets-only a public client ID, intentionally exposed in the client-side tracking snippet, is required. Affected versions extend through commit bad75bddc74d12d36cfb843f4531d3b830a8d994; the flaw is a moderate-severity integrity issue (CVSS 3.1 I:L) with no public exploit identified at time of analysis.
The TikTok for Business WordPress plugin (all versions up to and including 1.4.1) fails to verify authorization on its TikTok OAuth token-exchange handler, allowing an unauthenticated remote request to overwrite the merchant's stored TikTok integration access token in the wp_options table and effectively hijack the site's TikTok Business account and product catalog link. Exploitation is heavily constrained: the request must carry a valid TikTok OAuth auth_code issued specifically for that merchant's registered TikTok app, and the plugin only persists the new token after TikTok's API returns message='OK', so forged or arbitrary codes fail. No public exploit code or in-the-wild exploitation has been identified at time of analysis, and the vendor has committed a fix to the plugin's code repository; the impact is integrity-only (C:N/I:L/A:N), which keeps real-world risk low despite the unauthenticated network vector.
Unauthenticated information disclosure in the Bread WordPress plugin (versions up to and including 2.9.12) lets any remote visitor read the plugin's entire configuration export, including the PDF protection password stored in plaintext, by simply requesting the /?export-meeting-list=1 endpoint. The flaw is trivially reachable: the download_settings function is registered on the plugins_loaded hook and explicitly permits execution on non-admin public pages, so no authentication, authorization, or user interaction is required (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U, base 5.3 MEDIUM). Impact is bounded to disclosure of the stored protection_password rather than site credentials or code execution, and no public exploit code has been identified at time of analysis; the practical risk depends on how sensitive the protected PDF meeting lists and their shared password are in a given deployment.
Unauthenticated remote attackers can reach administrator-oriented REST API routes in the Mailchimp for WooCommerce WordPress plugin before 6.1.1 because the permission callback does not verify the requesting user's capability, allowing a persistent state change (CWE-862). Publicly available exploit code exists. The CVSS 3.1 vector is AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N, so the impact is limited to low integrity with no confidentiality or availability effect, but the unauthenticated nature and available exploit code make this a real, actionable priority driven more by exploitability signals than by raw severity.
Unauthenticated attackers can mark pending orders as paid in the Rede Itaú for WooCommerce plugin before 5.4.7 by abusing its PIX payment webhook, which fails to verify authenticity before updating order status. The issue affects stores running versions from 3.6.1 up to 5.4.7 with the PIX payment method enabled, requires no authentication or user interaction, and produces integrity-only financial fraud impact rather than code execution or data disclosure. Publicly available exploit code exists, and exploitation is straightforward once a pending order and reachable webhook are present; the vendor-released fix is version 5.4.7.
Authenticated users who hold the Hydra Booking 'host' role on a WordPress site can modify other hosts' profile data and reassign ownership of another host's record to themselves, because the plugin (versions 1.1.0 through before 1.2.3) does not verify that the host record being modified belongs to the requester. Publicly available exploit code exists, but there is no CISA KEV entry indicating active exploitation. The issue is a horizontal privilege-abuse/IDOR flaw rated CVSS 4.7 (MEDIUM) under the assessed vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N - the attacker must already possess host-level access and gains only limited, cross-host read/write capability, not administrative or site-wide control.
Unauthenticated attackers can publish arbitrary persisted query documents and claim (squat) query aliases on WordPress sites running the WPGraphQL Smart Cache plugin before 2.3.2, because the plugin neither requires authorization for the storage request nor validates the caller-supplied query identifier. WPScan reports that publicly available exploit code exists, though there is no confirmed active exploitation (not in CISA KEV); scoring is CVSS 3.1 6.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L) and the independent assessment characterizes this as a moderate, integrity-focused risk. Practical impact is bounded by whether the site actually depends on persisted queries and aliases and by a first-claim race - the attacker must register an alias before the site's own frontend does - and WPGraphQL's own access controls still govern what any stored query can return, so confidentiality loss is not demonstrated.
Unauthenticated visitors to WordPress sites running the Online Scheduling and Appointment Booking System plugin (versions 28.1 through before 28.2) can read other visitors' AI booking-assistant messages and inject new messages into their in-progress conversations, because the plugin's unauthenticated conversation actions never verify that the requester owns the conversation ID being referenced. Rated CVSS 4.8 (AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N) under CWE-639, the practical risk hinges on how conversation identifiers are generated: if they are sequential or guessable the flaw is broadly automatable, but if they are opaque tokens exploitation is opportunistic and low-volume, which is why the base score is only moderately elevated. Publicly available exploit code exists and the issue was reported by WPScan, though there is no evidence of confirmed active exploitation (CISA KEV) at time of analysis. There is no availability impact and no path to site takeover described; exposure is limited to the confidentiality and integrity of other visitors' assistant conversations.
Unauthenticated attackers can impersonate the Better Messages plugin's own internal AI bot accounts on WordPress sites running versions up to and including 2.15.33, gaining entry to administrator-restricted chat rooms and reading the private message history of other users. The flaw is entirely pre-authentication (CVSS vector PR:N/UI:N) and requires only that unauthenticated guest registration is enabled and that the server forwards the client-supplied X-Real-IP header to the plugin, which stores it verbatim; the plugin's is_ai_bot_user() check then prefix-matches the attacker-chosen value against 'ai-chat-bot-'. No public exploit code was identified at time of analysis and there is no CISA KEV confirmation of active exploitation, but the low complexity and lack of any credential requirement make the issue straightforward to abuse where restricted rooms exist. The vendor-assigned score is 5.3 (Medium, C:L/I:N); our reassessment raises confidentiality to High and adds a Low integrity impact because the same bypass allows posting into restricted rooms, netting a materially higher severity than the published vector implies.
Authenticated users holding only subscriber-level access can permanently delete arbitrary WordPress posts - pages, courses, quizzes, and WooCommerce products - on sites running the Tutor LMS plugin through version 4.0.8. The flaw is an authorization bypass: a lesson-deletion handler reaches wp_delete_post( $id, true ) without verifying the caller has capability over the target post, and the multi-stage exploit chain (create an authored attachment via the profile-photo upload flow, create a Tutor topic reparented to that attachment, then invoke the deletion handler) is required to satisfy the plugin's ownership checks. Wordfence reports it, vendor code changesets are referenced, and no public exploit code or confirmed active exploitation was identified at time of analysis; scored 4.3 by the reporter and assessed by our team as AC:H with moderate-to-low real-world risk, since authentication is mandatory and impact is limited to destructive integrity loss rather than code execution or data exfiltration.
SiYuan versions through 3.8.4 fail to enforce authorization on the getDynamicIcon endpoint, allowing authenticated attackers holding a read-only publish token to disclose metadata-such as block titles, names, aliases, and hierarchical paths-of restricted documents via a template injection triggered by type=8 requests. The flaw is rated medium severity (vendor CVSS 5.3, independent CVSS 3.1 5.3) and impacts confidentiality only; no public exploit or active exploitation has been identified at time of analysis.
HTTP request smuggling in Netty's netty-codec-http component lets unauthenticated remote attackers bypass front-end security controls by sending a crafted HTTP/1.1 chunk-size token containing whitespace after the hexadecimal digits, which Netty parses differently from other HTTP intermediaries. The flaw carries a CVSS 3.1 base score of 6.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L), meaning no authentication or user interaction is required, but integrity and availability impact is limited; meaningful exploitation generally depends on a multi-tier topology where a proxy, load balancer, or backend parses the chunk-size token inconsistently with Netty. Red Hat ships the affected library across a broad portfolio - including AMQ Broker 7, AMQ Clients, Quarkus, Keycloak and Red Hat Single Sign-On 7, JBoss EAP 7/8, Fuse 7, Data Grid 8, Camel for Spring Boot 4, Camel 4 for Quarkus 3, Apicurio Registry 3 and Debezium 3 - and no public exploit code has been identified at time of analysis, with no confirmed active exploitation (CISA KEV).
Unauthenticated tenants can read other organizations' uploaded files in CordysCRM (1Panel-dev) versions prior to 1.7.4, because the Shiro-configured anonymous routes /attachment/preview/{id} and /pic/preview/{id} resolve attachments through AttachmentService.getResource with a bare primary-key lookup and no ownership, organization, or permission check. Exploitation requires the attacker to know, guess, or observe a valid IDGenerator.nextStr file id; the ids are not sequentially predictable, which raises attack complexity, but ids leaked through shared preview links, logs, or browser history permit direct retrieval. The issue is read-only disclosure of stored files and is fixed in 1.7.4; no public exploit code or confirmed in-the-wild exploitation was identified at time of analysis. This is a genuine unauthenticated broken-access-control (IDOR) flaw but a moderate real-world priority, not a critical emergency.
Virtual host isolation bypass in IBM WebSphere Application Server and WebSphere Application Server Liberty, as bundled in IBM CICS TX Advanced 10.1, allows remote requests addressed to one configured virtual host to reach resources belonging to another virtual host on the same instance. The vendor assigns CVSS 3.1 6.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N, CWE-284); our independent assessment keeps the same unauthenticated, low-confidentiality/low-integrity, no-availability profile but raises attack complexity to AC:H because the weakness is only meaningful when an instance is configured to serve multiple distinct virtual hosts, while a default single-virtual-host deployment offers little to bypass. No public exploit code and no confirmed active exploitation (CISA KEV) were identified at time of analysis, and a vendor patch is available per the IBM advisory.
IBM WebSphere Application Server 9.0 and 8.5 allow remote, unauthenticated attackers to obtain sensitive file-system information through the FileTransfer servlet due to incorrect authorization (CWE-863). Exploitation requires network access to the servlet endpoint, which is part of the administrative/deployment interface, and impact is limited to confidentiality (CVSS 5.3, C:L). No public exploit code or active exploitation has been identified at time of analysis, but a vendor patch is available per IBM's advisory.
Unauthenticated network access to the SOAP/JMX administrative connector on IBM WebSphere Application Server 8.5 and 9.0 can bypass authentication, allowing an attacker to read limited information from the server (CWE-306, CVSS 5.3). The flaw is remotely reachable without credentials or user interaction (PR:N/UI:N/AC:L), but impact is confined to low confidentiality loss - no code execution, configuration change, or denial of service. A vendor patch is available per IBM's advisory; no public exploit has been identified at time of analysis, and real-world exposure is constrained by the fact that the SOAP/JMX connector is normally bound to a management interface that hardened deployments segment or firewall from untrusted networks.
