Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 22 Jan 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

European organizations using Horilla versions 1.4.0 through 1.4.x should prioritize upgrading to version 1.5.0 or later, where the vulnerability is fixed. If immediate upgrading is not feasible, organizations should implement network-level access controls to restrict access to the /recruitment/recruitment-details// endpoint, such as IP whitelisting or VPN-only access. Additionally, web application firewalls (WAFs) can be configured to detect and block unauthorized requests targeting this endpoint. Organizations should audit their current HRMS deployment to identify any exposure of unpublished job postings and review logs for any suspicious access patterns. Internal policies should be updated to ensure that sensitive recruitment data is not exposed via public or unauthenticated interfaces. Finally, organizations should monitor vendor advisories and community forums for any emerging exploit reports and apply security patches promptly.

Description

CVE-2026-24036 is a medium severity improper access control vulnerability in Horilla, an open-source Human Resource Management System. Versions 1.4.0 through 1.4.x expose unpublished job postings via an unauthenticated endpoint, leaking draft job titles, descriptions, and application links. This unauthorized access can reveal sensitive internal hiring information and disrupt recruitment processes. The vulnerability does not allow modification of data or system compromise but poses confidentiality risks. It has been fixed in version 1.5.

Impact

For European organizations, the unauthorized disclosure of unpublished job postings can have several impacts. Confidentiality of internal hiring strategies and workforce planning may be compromised, potentially revealing sensitive business information to competitors or malicious actors. This could lead to reputational damage if candidates or the public become aware of internal drafts prematurely, causing confusion and undermining trust in the recruitment process. While the vulnerability does not directly affect system integrity or availability, the leakage of internal HR data could be leveraged in social engineering or targeted attacks against employees or the organization. Organizations in highly regulated sectors or those with strict data privacy requirements may face compliance risks if sensitive personnel information is exposed. The ease of exploitation without authentication increases the risk profile, especially for organizations that have not updated to the patched version. The impact is primarily on confidentiality and organizational trust rather than operational disruption.

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
