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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system 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 Subsequent System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Disclosed: evidence found.

Detectable: no evidence on record.
No public nuclei template indexed

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 2026-10-25.

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

1. Restrict access to the PodcastGenerator episode upload form to trusted users only, minimizing the risk of privilege escalation. 2. Implement strict input validation and sanitization on the 'shortdesc' parameter to prevent XML injection and disallow external entity references or HTTP requests. 3. Employ network-level controls such as egress filtering and firewall rules to block unauthorized outbound HTTP requests from the PodcastGenerator server, limiting SSRF impact. 4. Monitor server logs for unusual outbound requests triggered by the application, which may indicate exploitation attempts. 5. If possible, run PodcastGenerator in a segmented network environment with minimal access to internal resources. 6. Stay updated with vendor patches or security advisories and apply updates promptly once available. 7. Conduct regular security assessments and penetration tests focusing on SSRF and XML injection vectors in the application. 8. Consider deploying Web Application Firewalls (WAF) with rules to detect and block SSRF patterns targeting the application.

Description

PodcastGenerator 3.2.9 contains a blind server-side request forgery vulnerability that allows attackers to inject XML in the episode upload form. Attackers can manipulate the 'shortdesc' parameter to trigger external HTTP requests to arbitrary endpoints during podcast episode creation.

Impact

For European organizations, exploitation of this SSRF vulnerability could enable attackers to probe internal networks, access sensitive internal services, or exfiltrate data indirectly by leveraging the vulnerable PodcastGenerator server as a proxy. Media companies, broadcasters, and content creators using PodcastGenerator may face risks of internal network exposure or lateral movement by attackers. While the vulnerability requires high privileges, if an attacker gains such access (e.g., via compromised credentials or insider threat), they could leverage this SSRF to escalate attacks or bypass network segmentation. The indirect nature of the attack means confidentiality and integrity could be compromised if internal services are accessed or manipulated. Availability impact is limited but could occur if internal services are disrupted. Given the medium severity and lack of known exploits, the immediate risk is moderate but warrants proactive mitigation to prevent potential exploitation, especially in environments with sensitive internal infrastructure.
