Exploitation Conditions

No special conditions - remote unauthenticated exploitation against the login service and APIs of the CreditNirvana Collections Platform (CollectionWorkz), consistent with AV:N/AC:L/PR:N/UI:N; the attacker only needs network reachability to the platform's authentication endpoint and crafts manipulated authentication requests. The description names no required feature flag, non-default configuration, or user interaction. The practical limiting factors are that the targeted instance must be network/internet-reachable to the attacker and that this is a niche, industry-specific product, so the exposed population is small; the exact affected versions are not stated in the available data.

Impact

This is a genuine high-priority issue, not a high-CVSS-but-low-real-risk case. All available severity signals align: the CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) describes a network-reachable, low-complexity, unauthenticated flaw with no attack requirements and no user interaction, scoring 9.3, and the vuln.today decision label is 'act_now' - the strongest urgency signal in the input. CWE-1390 (weak/improper authentication) is fully consistent with the description of an authentication-and-authorization bypass at the login service. The impact metrics (VC:H/VI:H, VA:N) match the description's claim that an attacker can read and modify sensitive data as an impersonated user but implies no availability loss. Counterbalancing signals: there is no EPSS score, no CISA KEV listing (CERT-In, an Indian national CERT, is the reporter rather than CISA), and no public exploit reference in the input, so there is currently no public exploit identified - the elevated urgency rests on the ease and impact of exploitation plus vendor/CERT reporting, not on observed in-the-wild activity. The practical risk is therefore concentrated on internet-exposed deployments of this specific product; organizations running CreditNirvana CollectionWorkz should treat it as act-now, while the absence of exploitation telemetry means widespread opportunistic exploitation has not been demonstrated.

Exploit ScenarioDerived

A remote, unauthenticated attacker who can reach the CreditNirvana CollectionWorkz login service sends manipulated authentication requests to the platform's APIs, bypassing session validation to establish a session as an arbitrary user - including an administrator. Because the CVSS vector is AV:N/AC:L/PR:N/UI:N, this requires only network access and no credentials, user interaction, or special timing. No public exploit is identified in the available data, so exploitation would require the attacker to independently develop the request manipulation.

AnalysisAIv1 – Oct 26, 2026

Improper authentication and authorization controls in the CreditNirvana Collections Platform (CollectionWorkz) login service let an unauthenticated remote attacker manipulate authentication requests and reach platform APIs without a valid session - enumerating users and establishing sessions as arbitrary accounts, including administrators, with the ability to read and modify sensitive data at that user's privilege level. The flaw is scored 9.3 under CVSS 4.0 (AV:N/AC:L/PR:N/UI:N with high confidentiality and integrity impact but no availability impact), and CERT-In has issued an advisory; the vuln.today priority is act_now. No public exploit code and no CISA KEV entry were identified in the available data, and the specific affected version range is not stated.

RemediationAI

No vendor-released patch or fixed version is identified in the available data, so the first action is to obtain the vendor's remediation guidance through the CERT-In advisory CIVN-2026-0523 (https://www.cert-in.org.in/s2cMainServlet?pageid=PUBVLNOTES01&VLCODE=CIVN-2026-0523) and confirm directly with CreditNirvana whether a corrected build exists. In the interim, because the only stated prerequisite for exploitation is network reachability to the login service and APIs, the highest-value compensating control is to remove that reachability: restrict the authentication endpoint and platform APIs behind a VPN or an IP-allowlisted reverse proxy so only known collector, agent and administrator networks can connect - the trade-off is that legitimate remote or customer-facing access breaks unless those source ranges are enumerated first. Put a reverse proxy or WAF in front of the login path to reject requests that carry session or identity assertions without a corresponding server-issued session, accepting that such rules require tuning against the platform's real login flow to avoid locking out valid users, and terminate authentication at an upstream gateway enforcing MFA where the platform cannot do so natively, at the cost of added latency and a second identity store to maintain. Treat the environment as potentially compromised: review platform and web logs for anomalous session creation, user enumeration patterns and API calls from sessions that were never preceded by a successful login, then invalidate all active sessions and rotate credentials for administrative accounts. Until an authoritative fix is available, the exposure window should be managed by network restriction rather than by detection alone.

Technical ContextAI · show details

The root cause class is CWE-1390, Weak Authentication: the platform's login service does not adequately verify that an authentication request corresponds to a legitimate, completed authentication exchange, and the authorization layer does not independently confirm that a caller holds a valid authenticated session before serving platform APIs. Because the trust decision rests on request-supplied state rather than a server-side validated session, an attacker who crafts authentication requests can have the platform mint or accept a session bound to an arbitrary identity, including an administrative one - a horizontal and vertical impersonation outcome. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N, VC:H/VI:H, VA:N/SC:N/SI:N/SA:N) and the independent CVSS 3.1 assessment (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N) agree that no privileges, user interaction or attack prerequisites are required beyond network reachability to the login endpoint and APIs. The supplied CPE (creditnirvana:creditnirvana_collections_platform_(collectionworkz), all version fields wildcarded) confirms the affected product but does not bound a version range, and the trigger mechanics beyond the login-service request handling are not described in the available sources. Note that availability impact is explicitly None in both vectors, so the expected impact is data disclosure and data tampering rather than service disruption.

DescriptionCVE.org

This vulnerability exists in the CreditNirvana Collections Platform due to improper authentication and authorization controls at the platform login service. An unauthenticated remote attacker could exploit this vulnerability by manipulating authentication requests and accessing APIs without a valid authenticated session on the targeted system.

Successful exploitation of this vulnerability could allow the attacker to enumerate platform users, establish sessions as arbitrary users including administrative users, access and modify sensitive information with the privileges of the impersonated user.

Executive ViewAI

Why It Matters

The CreditNirvana Collections Platform (CollectionWorkz) login service has a critical authentication bypass vulnerability (CVE-2026-110475) that allows unauthenticated attackers to impersonate any user, including administrators, and access sensitive data and functions. This puts the entire collections platform at risk of unauthorized access, data breaches, and fraudulent actions, with potential regulatory and financial consequences. Leadership must act immediately to mitigate this high-severity threat.

Business Impact: Severe
Compensating Controls

No vendor-released patch identified at time of analysis. Implement network segmentation, strict access controls, MFA, and continuous monitoring; deploy WAF with custom rules to detect and block authentication bypass attempts.
