"value": "A vulnerability in the `preprocess_string()` function of the `transformers.testing_utils` module in huggingface/transformers version v4.48.3 allows for a Regular Expression Denial of Service (ReDoS) attack. The regular expression used to process code blocks in docstrings contains nested quantifiers, leading to exponential backtracking when processing input with a large number of newline characters. An attacker can exploit this by providing a specially crafted payload, causing high CPU usage and potential application downtime, effectively resulting in a Denial of Service (DoS) scenario."

"value": "Una vulnerabilidad en la funci\u00f3n `preprocess_string()` del m\u00f3dulo `transformers.testing_utils` en huggingface/transformers versi\u00f3n v4.48.3 permite un ataque de denegaci\u00f3n de servicio (ReDoS) mediante expresiones regulares. La expresi\u00f3n regular utilizada para procesar bloques de c\u00f3digo en cadenas de documentaci\u00f3n contiene cuantificadores anidados, lo que provoca un retroceso exponencial al procesar entradas con un gran n\u00famero de caracteres de nueva l\u00ednea. Un atacante puede explotar esto proporcionando un payload especialmente manipulado, lo que provoca un alto consumo de CPU y un posible tiempo de inactividad de la aplicaci\u00f3n, lo que resulta en un escenario de denegaci\u00f3n de servicio (DoS)."

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
